O-FIST straps to your body by a built-in cockring that keeps the hand shaped plug in place no matter how hard you're pounding. Choose from three different styles based on your personal anal experience: SMALL, WIDE, and DEEP. JO-FIST SMALL is a little smaller than a standard hand, perfect for newbies looking to test the fisting waters. JO-FIST WIDE is for the more experienced anal player, it's modeled after a larger than average hand and designed to stretch you open. JO-FIST DEEP is definitely intended for experts, its length and width make it a truly formidable toy.
