After the success of our best-selling Humpballs Ring, we decided to develop a new version in the size of a standard cock ring: HUMPX. HUMPX is made from our signature FLEXtpr™ and is designed for comfort. This super-soft, stretchy ring hugs your goods for a greater bulge and pushes your package up and out. The flat inner side of the ring keeps HUMPX in place, preventing it from rolling or getting caught. HUMPX is also great for stacking on your sack like a carrier. Hump, pump, and unload your cargo with HUMPX. Material: Thermoplastic Rubber (TPR), phthalate-free.
