ZOID is a weird shape cockring, but it does stuff you want: it’s super rubbery but strong and bouncy when stretched…the shape is wider at the base narrow on top—this keeps ZOID positioned where you want, but adds more under-sack lift. That is more bulge, more lift, more of your hunky junk. This is what we call a “comfort” ring, its midsize for most everybody…it fits thicker junk, skinny junk, chunky junk, jumbo junk…it has a ton of stretch in a size that’ll make everybody bulgier. Our plus+silicone™ TPR/silicone blend: silicone for a smooth and warm feel, TPR for amazing stretch and strength. Phthalate free.
