Invasion Silicone Urethral Sound Set
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 urethra can accommodate the largest rod. Lots of water-based lube is a MUST.
