Made from silicone which is tasteless and odorless, it is ideal for insertion in the mouth. The Beginner Ball Gag is the perfect choice, as the outer mouth piece is contoured to fit comfortably. The original shape is based on an infant pacifier. The straps are leather that snap off so you can wash the silicone. <P> It's boilable, bleachable in a 10% solution, and dishwasher safe. Velcro closures on the straps allow for maximum adjustment for head size and ease of fitting. <br>Measures 1.6 x 2.5 inches.
