The Master Series Invasion Silicone Urethral Sound Trainer Set in blue is made from premium, phthalate-free, non-porous silicone that is easy to sterilise and body-safe. The flexible rods bend with the body as they slide in, giving the distinctive sensation that sounding offers. Each rod has two ends of differing thickness, so you can gradually build up until you reach the largest size in the set.
- Set of flexible silicone urethral sounds, each with two thicknesses
- Graduated sizing to build tolerance safely
- Rods approx 20.3 cm long, from approx 0.48 cm up to approx 0.97 cm diameter
