SSND-RNDMBALL 11-14mm
Recommended for open bore options
The SSND-RNDMBALL 11-14mm is an extra-long, heavy-gauge version of our RndmBall line, built for deep, full-length reach. Along its 17" length, 22 spherical nodes and tapered barrels graduate from an 11mm entry tip up to repeated 14mm peaks, rather than following one smooth taper.
Details
- Total length: 17"
- Insertable depth: 16.5" (419 mm)
- Entry tip: 11.0 mm (33 Fr)
- Maximum peak diameter: 14.0 mm (42 Fr), reached at several segments
- Final segment (22nd): 12.8 mm
- Retention valley: 9.0 mm (27 Fr)

| 7 | 13.5 mm | 18 | 13.8 mm |
| 8 | 13.5 mm | 19 | 13.0 mm |
| 9 | 13.5 mm | 20 | 13.0 mm |

| 11 | 13.8 mm | 22 | 12.8 mm |
How it works
The 11mm tip leads into 22 nodes that swell and ease irregularly rather than following a single taper, reaching the 14mm peak diameter at several points along the way. The final, 22nd node narrows sharply into a 9mm retention valley, letting the muscle close naturally ahead of the flared base.
Choosing your silicone firmness
Bob recommends #10 (Medium) as the default — it balances flexibility along the full 17" length while keeping the 14mm nodes well-defined for a crisp, rolling feel.
For an extra-plush, highly compressible feel that eases the 14mm peaks, #00-50 (Soft) is also available; for firmer tactile response, #18 (Firm) is an option too.
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 is an advanced piece — a 14mm maximum diameter repeated across a 16.5" insertable length is intended only for users who have already mastered standard intermediate sizes.
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.
