SSND-JWW 10mm-18.5mm
- In stock, ready to ship
Recommended for open bore options
The JWW Series is a smooth-taper stretching sound scaled precisely across 18 diameters, from 10mm up to 18.5mm (roughly 0.39"–0.73"). Every dimension — length, insertable depth, neck, and flange — grows proportionally with diameter, so the feel stays consistent as you move up in size.
Details
- Design: Smooth taper, no ribs or valleys
- Diameter range: 10.0 mm – 18.5 mm (18 sizes, 0.5mm increments)
- Core: Available solid or open-core

Choosing your silicone firmness
For the smaller sizes in this range (up to about 13mm), #10 (Medium) holds the taper's shape well during insertion. For the larger sizes (13.5mm and up), #00-50 (Soft) is worth considering, since the added material volume compresses more comfortably at those diameters.
Color options
#18 and #30 are available in pure translucent silicone.
#00-20, #00-50, and #10 use a translucent white base and can be mixed with our standard colors.
Please note
This series is intended for intermediate to advanced users progressing through sizes gradually, not for jumping straight to a larger diameter.
Use appropriate lubrication and never force insertion. Stop immediately if you experience pain, bleeding, or significant discomfort. Inspect the sound before each use and do not use it if damaged.
