SSND-SMTPR-5-10

The SSND-SMTPR-5-10 is a long, single-taper beginner sound — the expansion is spread across a full 8" insertable depth, so pressure stays low and even the whole way through, before dropping into a retention valley near the base.

Details

• Overall length: 8.5"
• Insertable depth: 8" (203 mm)
• Entry tip: 5 mm (15 Fr)
• Continuous taper: 5–10 mm (15–30 Fr) across the full 8" length
• Retention valley: ~7 mm (21 Fr)
• Base: 12.5mm (37.5 Fr) flared safety flange

How it works

The 5mm tip enters smoothly with generous lubrication, then the shaft climbs gradually to its 10mm maximum diameter over the full 8" length — since the taper is stretched out that far, there's no single point of sharp pressure. Just before the base, the 10mm peak narrows into a 7mm retention valley, letting the surrounding muscle collapse naturally into the groove and hold the piece in place.

Choosing your silicone firmness

Bob recommends #18 (Firm) or #10 (Medium) for this piece — a good middle ground that's still somewhat compressible but gives quicker structural feedback.

If you'd rather have a fully rigid column that holds its exact 5–10mm profile against tight muscle walls, #30 (Very Firm) is also available.

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 a beginner-friendly piece, between 5mm and 10mm to help build comfort and endurance gradually.
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.
