Stretchy Soft Dual Penis Cock Ring Cage and Sleeve Ball Sling Stretcher Oxballs invented the cocksling, Oxballs COCKSLING AIR is a lighter, pared-down version with less bulk but the same grippy bulge-making ability. It’s a c-ring + a ball stretcher + a shaft ring that adds squeeze for a bigger bulge. Slings wrap the base of the shaft and balls for 360 grips that don’t pinch or dig. Oxballs COCKSLING AIR can be worn longer than c-rings and Oxballs invented cockslings, so we make them fit and feel right. Less bulk more fun! Made of our amazing stretchy-strong Flextpr™, so much stretch it works for any size guy—it stretches 8X its size and snaps back for a perfect fit and the colors are shiny and lush.
