Master Series Urethral Sound Trainer Set is made of premium, phthalate-free and non-porous silicone, these urethral sounds are easy to sterilize and body safe for an all-new sounding experience.
These flexible rods bend with the body, sliding down your shaft for that unique sensation that 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!
