Take your pup-play to the next level with the FIDO cocksheath from OXBALLS. FIDO is made from our super-soft, stretchy flexTPR so it grips and melds to you like a rubbery second skin. The built-in COCKSLING at the base keeps FIDO firmly in place, even when you're pounding a puppy. (For some serious grip on your meat we recommend "burping" out any excess air by tightly squeezing the length of FIDO down to the base). If you want a tighter fit or more suction grip, FIDO comes with a nub insert that is designed to "lock" into the hollow chamber to shorten the inner length. Made of our softest, rubbery, incredibly stretchy flexTPRthe right smooth stretch that doesnt pinch. Phthalate free and no scent. LUBE SAFE: Water-based lube, hybrid or silicone lube recommended. Oil-base lubes not recommended. CARE: Wash after use in warm soapy water, air dry. Store toys separately: we recommend storing in breathable cloth pouches or for larger toys, in cotton socks.
