Filling their/your mouth, the gag's firm round shape prevents biting, spitting and backtalk. It buckles easily around the head, holding the breathable 1.6"/4cm sphere in escape-proof position. Two classic adjustable alligator clamps tipped in smooth black rubber dangle from the ends nice long chains - connect them to two silvery O-rings on either side of the gag, or set them free and use alone. If you decide to wear them together, the clamps will tug and pinch along with movement, another deterrent (or not) against sexy struggles. 

In ABS plastic, vegan leather and metal, the Breathable Ball Gag with Nipple Clamps can be spot cleaned as needed. Adjustable strap fits most.
