This Ball Gag is a black, padded device that will keep a submissive quiet. The gag is comfortably set into place with an adjustable strap in the back that firmly sets in. There's plenty of adjustable room to fit around a sub's head, but the ball gag, all 3.8 cm in diameter of it, will make sure that they can not talk. Lock not included. Can be used with or without a padlock.
