Isabella Sinclaire Silicone Urethral Sound Trainer Set

How the Set Feels in Use

These sounds are soft. Unlike rigid steel, each black silicone rod flexes and follows the body as it slides down the shaft, giving a yielding, gentle stretch rather than an unforgiving one. That flexibility suits newcomers to sounding and gives seasoned players a softer alternative to metal. Each rod is double sided, so a single piece gives you two different girths to explore.

Graduated Sizing and Progression

The set includes three sounds, each 8 inches long, with a slightly different diameter on each end. That gives you six girths in steady increments, so you can move up one small step at a time until the largest end feels comfortable.

• Small: 0.19 inch on one end, 0.23 inch on the other
• Medium: 0.27 inch and 0.32 inch
• Large: 0.34 inch and 0.38 inch
• Length: 8 inches per sound
• Color: black

Because every rod carries two sizes, the whole progression fits in three slim pieces. It is a compact kit that covers a wide range.

Materials and Construction

Each sound is made from premium, non-porous silicone that is phthalate-free and latex-free. The non-porous surface is easy to sterilize, which matters for a toy of this kind. With no metal parts, there is no hardware to inspect and no joints to wear out. Each sound is a single continuous rod of body-safe silicone.
