The silicone sounds are soft, flexible, and gentler than metal sounds so they are great for beginners and perfect for experienced users looking for a soft stretch. The graduated sizes make it easier for them to work their way up.

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!
