BULLBALLS-1 ballstretcher...it was our first and has been our most popular silicone ballstretcher...but the old the old molds we made this in were not up to our current standards...we create all designs now in CAD programs, we prototype on 3-D printers that allow us to refine and feels right...made of pure platinum cure medical grade silicone, (only the best from us pigs at OXBALLS), the stuff feels like skin-- warms up to body temp fast, keeps your balls sweaty and warm...and stretches your sack...gently...firmly, but without pinching, no blue balls... Item comes packaged in a heat sealed pouch
