SSND-SMTPR 14.5mm

The SSND-SMTPR 14.5mm uses a single, elongated taper spread across the full 6.5" insertable length, for a steady, low-fatigue stretch rather than distinct expansion stages, before dropping into a deep retention lock.

Details

• Overall length: 7" (177.5 mm)
• Insertable length: 6.5" (165 mm)
• Entry tip: 7 mm, expanding to 12 mm over the first 1.5"
• Main taper: 12 mm rising to 14.5 mm (43.5 Fr) peak over the remaining 5.5"
• Retention valley: 8 mm
• Base: Flat 16.5mm safety flange

How it works

The 7mm tip widens to 12mm over the first 1.5", then the shaft continues a slow, steady climb up to its 14.5mm peak diameter across the remaining 5.5" — a single continuous stretch rather than separate stages. Right before the base, the 14.5mm crest drops sharply into an 8mm retention valley, letting the surrounding muscle collapse into the groove and lock the piece securely in place.

Choosing your silicone firmness

For maximum comfort while stepping up to this size, Bob recommends #00-50 (Soft) — it's highly compressible and adapts continuously as you move. For a firmer middle ground with quicker structural feedback, #10 (Medium) 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

While the 6.5" insertable length is manageable, the 14.5mm maximum diameter puts this at an advanced level.
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.
