SSND-RIB-12mm
Recommended for open bore options
SSND-RIB-12mm is our largest ribbed silicone sound, designed to combine substantial volumetric expansion with continuous textured sensation along its shaft. Measuring 9.25" in total insertable depth, this model features a repeating series of raised structural ribs extending along the main body. The shaft begins with a highly polished, rounded entry tip for smooth placement before transitioning into the ribbed sequence, terminating at a solid proximal collar and a wide flared safety base. Available in solid-core or open-core configurations, the hollow option allows for natural fluid passage during use.
Anatomical Sizing & Mechanics
-
Polished Rounded Tip: Designed for smooth entry past the meatus to ease initial placement.
-
12mm (36 Fr) Ribbed Profile: Features a continuous sequence of pronounced structural ribs along a 12mm shaft, delivering steady internal contact during insertion and movement.
-
Smooth Proximal Collar: Transitions into a solid non-ribbed section near the base for comfortable placement against the meatus.
-
Flared Safety Base: Finished with an integrated safety flange for precise depth control and secure handling.
Anatomical Depth Guide
Providing approximately 9.25" (235mm) of insertable depth, SSND-RIB-12mm navigates through the pendulous and bulbar urethra, sliding past the external sphincter into the deep prostatic pathway. Its repeating ribbed geometry provides continuous, rhythmic sensation along the entire insertion path.

👑 Bob's Choice Recommendations
-
Experience Level: Intermediate
-
The Prime Durometer Recommendation: #00-50 (Soft) is the primary recommendation for this model. Choosing #00-50 allows the 12mm (36 Fr) ribbed profile to compress slightly during insertion, maintaining steady, gentle outward expansion pressure to stretch tissue comfortably.
-
The Alternative Durometer: Consider #10 (Medium) for users seeking firmer ribbed definition and stronger column support, or #00-20 (Very Soft) for maximum cushioned flexibility.
Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
