SSND-THREADED13
Recommended for open bore options
The SSND-THREADED13 pairs a long, continuously threaded shaft with a smooth, wide-gauge base segment — extended textured feedback up front, then a secure lock deeper in.
Details
- Total length: 8.75" (222.2 mm)
- Insertable length: 8.3" (209.5 mm)
- Entry tip: 12 mm, rounded taper
- Threaded shaft: 11.5 mm diameter, 13 cm ribbed section
- Retention valley: 12 mm ball dropping to 9.5 mm
- Smooth base segment: 13 mm (12.5 mm / 37.5 Fr), 5 cm long
How it works
The 12mm rounded tip opens the way with minimal resistance, then the shaft holds a continuous 11.5mm threaded texture for 13cm, delivering steady tactile feedback along the way. Past the threading, the shaft swells briefly to a 12mm ball before dropping into a 9.5mm valley, letting the tighter, less flexible entry muscle relax and grip the sound securely. From there, it scales back up to a smooth, straight 13mm for the final 5cm, resting in the wider canal beyond for a comfortable finish.
Choosing your silicone firmness
Bob recommends #10 (Medium) — it gives the 11.5mm threaded texture the structural definition to hold its ridges clearly, while keeping the 9.5mm valley strong enough to pass through the tighter entry muscle.
Color options
#18 and #30 are available in pure translucent.
#00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
Please note
This is an intermediate-to-advanced piece — the entry tip alone calls for a 12mm stretch, and the final segment reaches a full 13mm.
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.
