The SSND-MRB 10-14 is a long, 18-rib sound with a double-tapered entry and 17 ribs of varying length behind it, delivering a continuous rolling texture through its full 14.5" insertable length.

Details

  • Insertable length: 14.5" (368 mm)
  • First rib (tip peak): 14.5 mm (43.5 Fr)
  • Ribs 2–18: ~14.0 mm (42.0 Fr), varying 12–14.7 mm in length
  • Inter-rib valleys: 10.0 mm diameter, 4.5 mm long
  • Retention valley: 10.0 mm, elongated
  • Retention flange: 12.5 mm (1/2") length

How it works

The 14.5mm first rib delivers a strong initial stretch right at entry, then 17 more ribs — each around 14mm but varying slightly in length — run down a 13" section, separated by short 10mm valleys that let the surrounding tissue drop in and out as the piece moves. Past the final rib, the shaft settles into an elongated retention valley that lets the muscle close securely around it, just ahead of the flared base flange.

Choosing your silicone firmness

Bob recommends #00-50 (Soft) — it lets the ribs compress under pressure for a smoother, lower-fatigue feel over this length. Worth noting: one customer who ordered #10 in a bored version found the piece harder to push past deeper points, since the softer, hollow build can bend on the outside under resistance — solid or a firmer option may track more predictably if that's a concern.

For a firmer, more distinctly defined ridge-by-ridge feel, #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

With a 14.5mm entry rib, continuous 14mm ribs, and a 14.5" insertable length, this is an advanced piece intended for experienced users.
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.

I got this sound in 10 (soft) with a 1/8 bore. It was my first sound from SiliconeNozzles. I love this one but in the softness I got it in, it starts to get difficult to insert when it hits the bladder as it easily bends on the outside making it difficult to get it in further.
The ribs stimulate a lot and have led to some early and unexpected climaxes for me.
