Invasion Silicone Urethral Sound Trainer Set

Made of premium, phthalate-free and non-porous silicone, these urethral sounds are easy to sterilize and body safe for a new sounding experience. These flexible rods bend with the body, sliding down your shaft for that unique sensation you crave. Each sound is double-sided, with a different sized girth on each end. The graduated sizes allow you to work your way up until your stretched-out piss hole can accommodate the largest rod!
