Ok, so this was such a special Wonderful Treasure Find that, even though it was a bit beyond the pricerange we want to spend on our WTF items, we just had to buy it. It’s a sleep muzzle! It helps keep your mouth closed when you’re sleeping. Um. Yep!

Unfortunately, I’m not necessarily sure how to do any more research on this. I don’t know what to call it apart from a sleep muzzle. A night muzzle? Google’s only telling me about animals, but not humans, and I’m not sure if this is something that humans necessarily need. Or is this a Korean thing I don’t know about? Korean people: do you find yourself thinking of creative ways to keep your mouth closed at night? Well look no further, because this device is here to answer your prayers! I’m not sure why there’s a white girl on the cover. Maybe this is a European thing? Russian ladies: do you find yourself in dire need of keeping your mouth from dangling open at night? Do you see the onset of Flaccid Jaw Syndrome starting to set in? This here is going to help you survive!

Ok, no, really, I have no clue about this. Someone, please explain. Martina drools in her sleep. I yell in my sleep. Neither of those conditions for us would merit the use of this contraption. If there’s another reason you know, like maybe you get sore jaws at night, let us know, because we’re flummoxed.

Side note: maybe this is the anti-device to the mouth stretchers we saw a while ago?


Anyhow, if you don’t know the answer, then the best you can do is to click on this button below here, if you haven’t already. And if you do know the answer, you should still click on this button anyways. You’ll never know when you need a sleep muzzle in your life…

  1. I still say it looks like something you’d use to get your kink on. Ooh, you so nasty, S& M, with your S&M stuff, oooh!

  2. Ellin from Crayon Pop is a fan of this: http://youtu.be/LufVD-sIDys?t=8m41s

    OMG!! When I visit S. Korea next summer I have got to get one of those for my lil sister because she needs it. She has a problem with keeping her mouth closed and causes her gums to swollen..plus she also sleeps with her mouth wide open LOL

  5. Katrina Vineles Wilchez

    i really wanted you guys to do 2ne1, ive been waiting all week….

  6. kpopfan123

    I think it’s for snoring…


  7. Vampires walking in while you sleep……. Martina needs to watch ‘Vampires Suck’ (Twilight Parody) Bella is not a pretty sleeper in that movie. >:D

  8. maybe it’s for Kpop people who have extreme cases of flaccid jaw syndrome :D

  9. 1. With so many mouth related WTF products in Korea, I wonder if many in Korea have not developed past Freud’s oral fixation stage of psychological development.

    2. This muzzle makes the icky head gear and retainers of my childhood seem like a holiday.

    3. I can’t help but think that waking up and looking like sausage face would not be a welcomed event in any bedroom no matter how much love was present.

    4 . Could Hannibal Lecter have been the key designer in this particular piece of sleepy time torture device? In which case anyone named Clarice should avoid this product!!

  10. Honestly, this device would probably be useful for me when I sleep… =Q= lol

  11. Are they not doing K-pop chart updates anymore? :(

  12. To help Jonghyun keep his mouth closed on variety shows.

  13. Hahahahahahhaa MARTINA – your sleeping story ROCKED :D When you told about the calculator I cried so much from the laughter! :)) IT was AWSOME!!! HAHAHAHAH – oh and i also drool, sometimes! ;)

  14. KATHyphenTUN

    In conclusion, these are used to keep vampires away! LOL
    Oh boy! that mouth stretcher episode I remember watching that and being in tears from laughing so hard!!! Maybe I shouldn’t re-watch it at night when people are sleeping…..

  15. dad’s bday present


  17. I don’t want to be captain buzzkill but I’ve had a history of Sleep Apnea which is basically the worst thing on earth. When you breathe through your mouth you have a propensity to snore, which means you’re not getting enough oxygen while you sleep, ruining your sleep cycles and rhythms, and it really hurts your day to day life because of how tired and groggy it makes you. Also, sleeping with your mouth open can lead to teeth grinding, waking up severely dehydrated, and more.

    By having a mask like this (or well, hopefully something more professionally made) it will help you have a better nights rest, lower the risk of Sleep Apnea, and more.

    Sooooo I can see where the IDEA of this device is useful, though in practicality it just looks weird.

    • Sleep apnea is terrible. Sorry to hear that. I hope you can (or are currently) seeing a sleep doctor for it. BTW~ My mom has sleep apnea too but she uses a medical device that is like an oxygen machine which is hooked up to an oxygen mask that is plastic. It looks nothing like this mouth muzzle. I believe this machine she uses is the only type of medical device allowed to be used that I know of (at least the US) to help sleep apnea. My mom (like most sleep apnea people) stops breathing at night and that mouth muzzle (that is in the video) would make it harder for her to breathe and it would probably kill her. No one should use this mouth muzzle to help with sleep apnea. My mom suffers a lot too so it’s got to be horrible for you. I hope you can get the help you need. :)

  18. Oh Si-moon and Mars-tina (Space nicknames!!), this video was hilarious! I wonder whose idea it was to make the “muzzle” in the first place? *Ponders Deeply*

  19. Omg I reeeeealy think I know what this is for!
    Wouldn’t it help with snoring?! Most snoring is caused by your jaw moving back pressing against your wind pipe slightly, to the point it causes the sound. So I think the mask is making it stay in place lol

    I would love to try this out on my parents who snore loudly OTL

  20. OMG! when I first played the video I was like “omg, it’s perfect for my husband as he always leaves huge saliva stains on the pillow”, but when I saw how Martina looked with that on I changed my mind, I don’t wanna wake up next to Hannibal the Cannibal Lecter :))

  21. I don’t think I have ever laughed this much before even watching the video :D This has to be your funniest video thumbnail ever! And the video made me laugh as well, this thing is pretty horrendous and the cherry patterned fabric makes it even funnier. If we cover this with cute fabric, will no one notice that it looks creepy as hell?
    In my case the weird thing is that I almost always drool if I’m taking a nap in the afternoon but hardly ever when I’m falling asleep at night. It could be useful when I’m falling asleep in a bus/car because then my neck bends backwards and my mouth tends to open but I don’t want to look like Hannibal Lecter meets S&M (and by S&M I don’t mean Simon and Martina) in public transportation.

  22. Noel

    A truly original sentence that has never been uttered before: “We’re low on drool, lets make more”.

  23. Hahahaha I seriously doubt I could sleep with that on, I’m good with my drooling problems we are working it out xD

  24. I, too, have a drooling problem D: Every day when I wake up first thing I do is rinse my face to get the drool stains off. I don’t think this would help, I think it’d just annoy me and make it harder to fall asleep (I have insomnia so that’s another issue). It’s like face bondage :P

  25. hysterical!!

  26. this thing could be used as a punishment for the wank challenge XD

  27. thisisjustforfunval

    This week’s and last week’s crazy contraptions created a merger in my mind of Hannibal Lecter and What Every Happen to Baby Jane. They should make that a film.

  28. If you put that on a drunken friend, wouldn’t that risk said friend asphyxiating on their vomit? o.0

  29. I can’t masturbate to this…(sorry, too much youtube)

  30. O___O that is messed up son….

  31. That is the t-shirt I sent (the Avengers one)! Must of been to small for you, Simon. Oh well, it looks great on Martina.

  32. Kinda legit, considering you “supposedly” eat 8 spiders a year in your sleep.

  33. Martina, you cut your own shirts, don’t you? You should do a Open the Happy video about that.

  34. FJS is a very real and prevalent problem in Kpop. Maybe it’s to train your jaw to stay shut, so when you’re awake, it doesn’t hang open vapidly.

  35. That was freaking HILARIOUS!! I lost it when Simon try to open his mouth really wide with that contraption on lmfao!! So glad this segment is back! I also hope the WANK challenges are here to stay as well. (I have been wondering where they went, so I’m excitedly waiting for the next WANK to upload).

  36. Cyber_3

    Wow, what a creepy device. I’m not sure how it could stop you from snoring (since that’s through your nose) and if your nose is stuffed up won’t you keep waking yourself up because you can’t breathe? I wonder if this actually gives you sleep apnea so that you can look cute while you are asleep? Weird.

    On a side note: though it’s not an incredibly close shot, I’m pretty damned sure that the model on the package is Asian and not “white”. You are making the assumption because she has blond hair but if you look more closely at the eye and nose shape, I think you’ll find that she’s like SooZee – Asian with blond hair. Does bleaching your hair give you night time sleepy troubles? ;)

  37. So funny story how my dad and grand mother both have to wear something similar to bed it has to do with there sleep apnea and using c-pap machines when they sleep because both of then have the masks that only attach to the nose. using a strap in conjunction.reminds your body to breath through the nose and helps them breath better threw the night. maybe it has to do with snoring?

  38. I’m willing to bet it’s supposed to stop you from snoring. Although there could be other “benefits”!

  39. Keeping your mouth open at night could cause problems I guess. Dry throat, more susceptible to sickness, irritation, bacterias etc. Drooling is just a minor problem, snoring.. Don’t see the reason how it would help with teeth grinding, maybe discourage it, which is very bad for teeth. I want to buy this for a family member :D

  40. It looks like something to prevent a double-chin. But I checked Amazon & it said this:

    “The Mouth Strap is designed for those who breathe through mouth during sleep.
    Finds relief from snoring / Puts a stop to dry mouth / Prevents a saggy and unhealthy looking face
    Simply wear the mouth strap on your chin and hook the strap around the ears
    Comfortably supports your jaw while sleeping / It is handmade by professionals. / extremely lightweight / Adjustable Strap / One size fits all / Made with 100% Cotton for Skin
    The Mouth Strap is the ideal solution to prevent mouth breathing during sleep.”

    Still am not exactly sure what the point is.

  41. lol is like boundage for …face?

  42. Hey guys!
    I’d like to know if the T-Shirt Martina is wearing is the same one that was in one of your fanmails? If yes, did you cut the sleeves off yourself? It looks really cool! :D

  43. Sonia

    Definitely DO NOT wear that if you’re drunk, lest you “Jimi” yourself after you pass out

    But if your mouth falls open unattractively when you sleep, go crazy

  44. Keeps the spiders away :D

  45. Guess it’s a good thing for people who drool a lot.. as for me.. friends told me I speak from time to time.. funny thing though.. we were 3 girls in a hotel room and our friend told us we hold a conversation for like 2 minutes.. but she didn’t understand what it was about.. xDD

  46. Is it just me, or the video looks… smaller? like, before it was much bigger and wider, but now it kind of shrank in size?

    P.S. 나 으르렁 으르렁 으르렁 대, 나 으르렁 으르렁 으르렁 대, 나 으르렁 으르렁 으르렁 대

  47. Haven’t even watched the video yet, but the video icon brings a whole new definition to WTF with S&M. Whooo! Hahaha.

  48. I found some info on the product in Korean, and not surprisingly it seems to be linked to the two of the most important themes in Korean advertising: beauty and success.

    Here are the reasons it says you should wear this torture device to bed, and force your children to do so too:

    If you breathe through your nose, your brain becomes sharper.
    Breathing through your mouth is a bad habit that lowers your immunity to germs.
    Breathing through your mouth due to a stuffed-up nose has a bad influence on childhood growth and marks at school [they relate this later to ADHD - apparently breathing through your mouth "decreases your attention span"].
    The most important thing for maintaining your face’s beauty is to breathe through your nose [Why?? Will your nose deflate if you breathe through your mouth?].
    Breathing through your nose is better for your overall health.

    Impressive!! Why not just wear it all day long?!

  49. Sleep Muzzle: To help k-pop stars who always have their mouths hanging open.

  50. this thing is really nasty :D

  51. really putting the S&M in Simon & Martina with this week’s WTF…

  52. haruchi

    Hm… I think you should test it when you’re sleeping before giving it the final verdict! It might work… Maybe it could stop snoring too. (I could buy one for my dad then. haha)

  53. I say it’s meant to keep your mouth closed so bugs don’t crawl in while you’re sleeping. I have arachnophobia and every time I tell people that they always have a need to inform me about the statistic on how many you eat in your sleep during a year. This is a perfect prevention device…if you can handle the weird lines in the morning.

      Don’t worry about that, it’s a myth. Do some research on it and you will find that out. There are so many factors that just make this not probable at all. One, a spider isn’t stupid and isn’t going to walk into this damp humid hole that is breathing, they know that’s another creature and it will be killed. Two, your lips and tongue are super sensitive and if something were to brush up against them at night your brain would kick into defensive mode and you would automatically brush it away, or turn your head, or maybe even wake up from the startle. I could go into more, but that’s not really the point of this thread. I just thought I would allay your fears so maybe you would sleep better at night :)

      • That’s not necessarily true… in college my boyfriend at the time was in the army and brought back a family of brown recluse in his rucksack after a survival weekend. They infested my room and I ended up hospitalized from 6+ bites that happened in my sleep. I woke up sick and coughed up 2 baby spiders in the sink, if it wasn’t for that I wouldn’t even know where the bites came from. I’ve also caught them walking on my face without realizing it and the cat smacking me awake (he sleeps on my head/pillow.

      • That’s actually quite helpful. Thanks :)


  55. If there were aegyo horror movies, this is what it would look like…

  56. Actually many idols use this thing, like all the time :P

  57. i thought this was some sort of torture device at first ._________________.

  58. I think it could be for people who grind their teeth at night. Not sure if it would work though……

  59. My first thought was that it makes the person look like Bane xD

  60. OMG Finally. Sydney-ers I have got access to the main website :D HOORAY!!! Been a while :D

  61. Amy Konoka Agnew 에이미

    My first thought was to stop men sticking their penises in while you’re trying to sleep…:/

    • I don’t think you’re alone in thinking that…

      • Amy Konoka Agnew 에이미

        ooo, just while I have your attention, what’s the chances you think you could arrange an interview with WonderBoyz? They really deserve some attention! Thanks for replying :)

        • I agree their company even subs their videos for international fans which is really nice. They usually but up the korean one then the subed one later on.

        • Usually S&M are not the ones to seek out interviews. What happens is that the company the groups or individuals come from notice EYK and contact them to ask about arranging an interview. How the companies sometimes notice EYK is because of awesome fans who send tweets and letters about having an EYK interview. That’s exactly how they interviewed the awesome Moofbooty aka MFBTY aka Mother F@&$ Bizzy Tiger Yoon Mirae.

          So if you want an interview you can try to mobilize the fans to bring the wonder boys company’s attention to EYK and see if they would be interested in asking for an interview.

        • Amy Konoka Agnew 에이미

          Oh! Thanks for the info, will definitely try this!

        • That’s true but they also said they were also now asking companies with the help of Suzy

        • A wonderboyz interview would be great
          I would also be all over a nu’est interview. They have an english speaking member so it would probably go quite smoothly.

    • Seeing as Koreans assume Russian women are prostitutes…… that would explain why there is a Caucasian woman wearing this (on the packaging). Let’s your clients know you don’t do oral.
      Just kidding!
