The 3-gag training system allows you to start with a small gag and gradually work your way up to the larger one - and go from mild to wild as you progress! Each gag is interchangeable using the snaps, made from non-toxic plastic and fitted with holes to make breathing easy. The sturdy black leather strap easily adjusts to fit most sizes, giving you instant control over when, and how often, your lover speaks. You\'ll teach your partner the meaning of submission in no time at all - remember practice makes perfect! S: 4 cm M: 4,5 cm L: 5 cm
