Oxballs has invented the Cocksling. The Cocksling Air is a lighter, streamlined version with less volume but the same gripping bulge design. It functions as a C-ring, a ball stretcher, and a sheep ring, adding squeeze for a larger bulge. The loops wrap around the base of the shaft and the balls for a 360° grip that does not pinch or cut in. The Cocksling Air can be worn longer than C-rings, and Oxballs has designed the Cockslings to fit properly and feel great. Less mass, more fun! Made from our amazingly stretchy Flextpr™, which is so elastic that it accommodates any male size - it stretches up to 8 times its size and snaps back for a perfect fit. Material: Phthalate-free thermoplastic rubber (TPR).
