SSND-Diamond 8-23

The SSND-Diamond 8-23 is an elongated, large-diameter piece in the diamond series — a smooth taper from a slim 8mm tip up to a substantial 23mm swell, for significant volumetric stretching.

Details

Entry tip: 8.0 mm (0.315", 24 Fr)
Maximum mid-shaft swell: 23.0 mm (0.906", 69 Fr)
Retention valley: 13.0 mm (0.512", 39 Fr)
Insertable depth: 3.0" (76 mm)
Overall length: 3.6"
Safety base flange: 1.5" (38.0 mm)

Choosing your silicone firmness

Given the substantial 23mm expansion, Bob recommends #10 (Medium) — it balances flexibility for comfortable insertion with enough structure to hold its shape.

For maximum compliance during high-diameter stretching, #00-50 (Soft) is also available; for maximum firmness and precise control, #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

At 23mm, this is an advanced-sizing piece intended for users who are already experienced with large-diameter 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.
