This steel mouth gag is suitable for you who has experience with using gags.
The special thing about this gag is that the part intended to be in the mouth is made as an O-ring. The ring should sit behind your teeth so that it does not fall out.
Four metal whiskers are mounted on the ring which sits close to your face when you use it. These whiskers ensures that the O-ring doesn't disappear in your mouth.
The gag stays in place thanks to a strap which goes all the way around your head. The strap is adjustable and can fit heads with a circumferences of up to 58 cm. There is even place enough to make more holes in the strap if need be.
All in all it is a very stylish mouth gag.
