SSND-MD 10-18

Advance your routine to the next tier of wide-gauge calibration with the SSND-MD 10-18. Engineered as a longer, thicker evolution of our multi-dimensional flexible stretching series, this premium platinum-cured silicone sound satisfies the popular demand from users of our 8-16mm series who are ready for the next milestone in size and length. Featuring an expertly calculated 8-segment profile, it provides a highly stimulating penetration as each consecutive segment gently spreads and readies the pathway for the next slightly larger ridge.

Sequential Multi-Diameter Ridge Mechanics: The architectural layout of the MD 10-18 focuses on a smooth, wave-like expansion sequence that minimizes friction while optimizing tissue dilation. As detailed in the official production specifications the sizing breakdown flows through 8 distinct expansion zones:

 
This specialized sequence kicks off with a smooth, rounded tapering tip measuring approximately 8.5mm to ensure an effortless, non-binding introduction at the Meatus. As the probe transitions deeper, the alternating ridges and shallow relaxation valleys ensure that the canal receives localized relief between expansion peaks, reducing fatigue during deep sessions.

Anatomical Design & Shared Dimensions:

• Insertable Length: Features a generous 7 inches of usable, fully insertable depth up to the base flange.

• Sizing Profile: Transitions seamlessly from an 8.5mm entry tip up to an impressive 18mm (54 French) maximum diameter ridge.

• Retention Valley: Sculpted with a pronounced 13.5mm (40 French) deep retaining valley positioned perfectly in front of the base. This deep groove allows surrounding muscle walls to comfortably collapse behind the main shaft, securing the sound reliably in place.

👑 Bob's Choice Recommendations

• Experience Level: Advanced. Spanning a 7-inch insertable footprint and scaling up to an 18mm maximum diameter, this instrument is built specifically for seasoned users moving into advanced deep stretching.

• The Firm Performance Level (Bob's Prime Recommendation): For this particular model, Bob highly recommends ordering in our #10 (medium) material composition. While remaining flexible in the smaller forward regions, this durometer provides a moderate, highly satisfying level of stiffness. It ensures that all 8 progressive expansion segments maintain their precise ridges under internal muscle pressure, delivering a definitive and highly effective stretching session.

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.
