Choosing your silicone firmness

For the SSND-MRB 8–10, Bob recommends #10 Medium. The firmer silicone provides more structural support and helps prevent the sound from bowing or buckling during insertion.

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-MRB 8–10 gradually increases from an 8.4 mm entry tip to a 10 mm final rib. It is a relatively small graduated sound compared with the larger MRB models.

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.
