SSND-Diamond 11-18
Recommended for open bore options
The SSND-Diamond 11-18 is a mid-sized stretching plug — a slender tapered tip that expands to an 18mm diamond-shaped swell before narrowing into an 11mm retention valley, seated against a wide flared base.
Details
- Maximum diamond swell: 18 mm (0.709", 54 Fr)
- Retention valley: 11 mm (0.433", 33 Fr)
- Insertable depth: 2.75" (69.85 mm)
- Overall length: 3.25" (82.5 mm)
- Base flange: 1.3" (33.0 mm)
Choosing your silicone firmness
For the SSND-Diamond 11-18, Bob recommends #10 (Medium) — it balances flexibility for comfortable insertion with enough body to hold the diamond shape.
For maximum cushioned comfort during extended wear, #00-50 (Soft) is also available; for added column rigidity during placement, #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
The 18mm swell is a meaningful step up in stretch, so this is best suited to users who already have some experience with mid-size stretching.
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.
