Invasion Silicone Urethral Sound Trainer Set

Three flexible silicone rods that let you start small and stretch up at your own pace. Every sound is double-ended, so this one set gives you six diameters, from a gentle .19 inch tip up to a filling .38 inch.

Features

• Set of 3 graduated sounds, each 8 inches long and double-sided (six sizes in total)
• Diameters: small .19 in / .23 in, medium .27 in / .32 in, large .34 in / .38 in
• Soft, bendable silicone that moves with your anatomy instead of forcing it straight
• Phthalate-free, non-porous, and body-safe
• Smooth blue finish with no seams to catch on the way in

Materials & Care

Made from non-porous silicone. Wash with warm water and antibacterial soap or boil a few minutes to sterilize. Use plenty of sterile water-based lube every time, and don't share without a barrier.

FAQ

Are these okay for a first-timer?

Yes. Begin with the .19 inch end, take it slow, and only step up a size once the smaller one slides in comfortably with no strain.

What lube should I use?

Sterile water-based lube is the only safe pick here. Skip silicone lube since it can break down silicone toys, and use more than you think you need.

How do I clean them?

Wash before and after every use with warm water and antibacterial soap, or boil for a few minutes. The silicone is non-porous and heat-safe, so it holds up to real sterilizing.
