Looking for the perfect-sized ball gag but none of them seem to fit? With a few squeezes of the medical-style pump ball, this latex gag (original size 3.5 x 1.75 inches) quickly inflates to fill any size mouth. To relieve the pressure and deflate the gag, simply press the quick-release valve and it shrinks to its original size. The strap adjusts to fit circumferences of up to 24 inches. A free eye mask is also included.
