Color

The SSND-BMK2 is a flexible silicone urethral sound with a rounded tapered tip and two enlarged 11 mm (33 Fr) barrel sections near the base. The shaft changes diameter between the tip and the two barrels before narrowing to a small retention valley just ahead of the flange.

Details

  • Tip: 8 mm (0.315", 24 Fr)
  • First section: 9.5 mm (0.374", 28.5 Fr)
  • Intermediate sections: 9 mm and 8.5 mm
  • Two enlarged barrels: 11 mm (0.433", 33 Fr)
  • Retention valley: 5.5 mm (0.217", 16.5 Fr)
  • Insertable length: approximately 6" (152 mm)

Choosing your silicone firmness

For the SSND-BMK2, Bob recommends #00-50 Soft. The softer silicone allows the changing diameters to compress and flex more easily.

Color options

#18 and #30 are available in pure translucent silicone.

#00-50 and #10 use a translucent white base and can be mixed with our standard colors.

Please note

The SSND-BMK2 has multiple diameter changes along its length, including two 11 mm barrels. It is intended for users who are already experienced with urethral sounds of this size.

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.
