SSND-MRB 7 Rib 11.5-14.5mm

SSND-MRB 7 Rib 11.5-14.5mm

The SSND-MRB 7 Rib 11.5-14.5mm follows the design of our long-standing 11-14mm model, with seven ribs stepping up to a 14.5mm peak at the third rib for a pronounced point of stretch.

Details

• Insertable length: 7.75" (197 mm)
• Overall length: 8.25" (210 mm)
• Entry point: 11.5 mm (34.5 Fr)
• Peak rib (3rd): 14.5 mm (43.5 Fr)
• Shaft profile range: 11.5–14.5 mm (34.5–43.5 Fr)
• Retention valley: 9.7 mm (29.1 Fr)
• Safety flange base: 17.7 mm (0.70")

How it works

The tapered 11.5mm entry tip guides initial placement, then the ribs step up to a 14.5mm peak at the third rib — the primary point of stimulation — before the profile relaxes back through variable diameters over the remaining shaft. The final rib narrows into a 9.7mm retention valley, letting the muscle anchor just ahead of the wide 17.7mm base flange.

Choosing your silicone firmness

Bob recommends #10 (Medium) as the default — it prevents the shaft from bowing or buckling during insertion while delivering crisp, well-defined feedback across each rib.

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 falls in our intermediate, 12–15mm diameter tier.
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.
