SSND-MRBCUBE

Experience a uniquely textured approach to linear tissue training with the SSND-MRBCUBE. Crafted with a specialized, four-sided squared cross-section, this sound provides an exceptional blend of multi-dimensional geometric feedback and flexible depth pathing. Every edge along the shaft is carefully, softly rounded to guarantee that there are no sharp or harsh points, allowing the unique cubed nodes to engage internal muscle walls smoothly and comfortably.

Anatomical Sizing & Squared Segment Mechanics: 

• The Micro-Tapered Entry Tip: Starts with a sleek, non-aggressive 4.5mm (14 French) tapered tip that establishes a smooth, immediate entry point through the Meatus when paired with adequate high-quality water-based lubrication.

• The 15 Multi-Sided Ribs: Features 15 separate, squared-off ribbed segments that vary slightly in linear length (ranging from approximately 13mm to 25mm). These distinct blocks provide a fascinating, rhythmic transition of tactile pressure as they slide through tissue.

• The Relief Valleys: The transitions between the 15 segments drop into uniform 8mm (24 French) valleys, allowing tight canal walls a momentary point of relaxation between nodes.

• The Retention Flange: Concludes with a narrowed 7mm (21 French) retaining valley positioned immediately before the flared flange. This specialized anatomical zone allows the primary sphincter muscle to contract snugly into the groove, anchoring the 12-inch column firmly in place.

Anatomical Depth Guide: Boasting a total length of 12 inches with an impressive 11.75-inch (298mm) insertable length up to the safety stop, this highly flexible piece is built to safely map the entire length of the urethral tract:

• 11.75 Inches: Spans the remaining deep tract to comfortably cross the internal sphincter and enter the bladder neck, offering an incredibly immersive, full-length presence.

👑 Bob's Choice Recommendations

• Experience Level: Beginner. Calibrated with a 4.5mm entry tip that steps up to 8–9mm squared expansion zones, this model is an excellent piece for advancing beginners to intermediate users wanting to move beyond traditional round rods into rich, multi-sided geometric surfaces.

• The Prime Durometer Recommendation: For an intricate, multi-segmented piece like this, Bob highly recommends ordering this model in our #10 (medium) or #18 (firm) material compositions.

• The High-Flex Alternative: If you are using this 12-inch piece for long-duration deep canal wear and want the squared nodes to feel highly compressible, plush, and skin-like against sensitive walls, selecting our #00-50 (soft) material option delivers a wonderfully giving experience that yields comfortably to natural movement.

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.
