Why You'll Love It

Train and track your progress. A unique scale design makes every advance clearly visible—record the width you reach each session for a real sense of achievement.

Progressive dilation. Three graduated widths let you move from small to medium to large, gradually building tolerance and stamina.

Full, satisfying sensation. A tapered end eases in, then gradually widens for better dilation—feel the shift from emptiness to fullness.

Controlled, secure play. An O-shaped carabiner clip lets you control the speed and rhythm, prevents slipping, and even clips to your pants to carry along.

Smooth and comfortable. Stainless steel has no sharp gaps or cracks for a comfortable experience.

Waterproof and easy to clean. The waterproof design makes cleaning simple and invites playful use in the bath.

How to Use

Start with the small (S) sound and work up to medium and large over time.

Clean thoroughly and apply a generous amount of water-based lubricant to the sound and urethra.

Insert the tapered tip slowly and gently, easing in as the width gradually increases.

Use the carabiner clip to control rhythm and prevent slipping; note the scale reached to track progress.

Remove gently and clean thoroughly after use.
