Master Series Invasion Silicone Urethral Sound Trainer Set offers a structured, progressive introduction to sounding with three flexible, double-ended rods in graduated sizes. Each sound carries a different girth on each end, giving you six diameters to explore so you can advance gradually and comfortably at your own pace.
Crafted from premium phthalate-free, non-porous silicone, the rods are body safe and easy to sterilize between sessions. The flexible material bends with the body, following natural curves for smooth, controlled insertion and a distinctive sensation. Always use a generous amount of sterile, water-based lubricant and take your time moving between sizes.
Graduated training is what sets the Master Series Invasion Silicone Urethral Sound Trainer Set apart. Start with the slimmest end at 0.19 inches and work up through the medium rod to the largest end at 0.38 inches as you grow more experienced. At 8 inches long, every rod offers plenty of length for a secure grip during play, and the vivid blue finish keeps the set easy to identify.
