SSND-RNDMBALL 10-13

Built directly in response to customer demand for robust, larger-diameter custom sounds, this platinum-cured silicone sound utilizes an undulating multi-ball style shaft and an elegantly contoured tip to deliver a deeply satisfying, variable stretch. By blending distinct spherical sections with longer, gradually tapered barrels, this probe continuously shifts its physical presence to provide individualized depth control and outstanding tactile variety.

Anatomical Sizing & Dual-Length Node Mechanics: 

• The Smooth Entry Tip: Both models begin with a marginally tapered mini-ball style rounded tip measuring 10mm to establish an approachable introduction.

• The 8-Inch Short-Stature Model: Features the first 12 separate expanded ribbed areas, transitioning smoothly from the 10mm tip up to a localized 13.2mm peak at segment 9, before dropping to a 12mm retention seat. This provides a compact, heavy-volume training experience focused entirely on the high-grip entrance zones.

• The 17-Inch Full-Length Model: Carries out the complete 22 separate expanded ribbed areas that continuously fluctuation in shape, length, and diameter, hitting an overall 13.3mm maximum peak at the 20th segment for deep, rolling muscle stimulation.

  • The Flanged Retention Lock: The final ball tapers to a broad 13.1mm profile to provide a gentle, localized stretching action. This drops immediately into a narrow 9mm retention valley situated directly ahead of the safety flange to let the primary entry sphincter muscle close naturally around the groove, anchoring the probe securely in place for a stable fit.

Anatomical Depth Guide: Available with an option of either a 8-inch insertable depth or a comprehensive 16.5-inch (419mm) insertable length up to the flanged base (17 inches total length), this highly flexible sound adapts to your boundaries. The full-length 16.5" model is built to cross past the bulbar bend and line the deep prostatic pathways, while the 8" model allows for concentrated, low-fatigue sphincter expansion.

Note: The 8-inch model terminates after the 12th segment transition.

👑 Bob's Choice Recommendations

• Experience Level: Advanced. Because of its high-volume 13.3mm node expansions and potential 16.5" full-length configuration, this custom sound is designed for advanced users who have mastered standard intermediate sizes and want a substantial, shifting profile.

• The Prime Durometer Recommendation: To make these large, 13mm+ spherical transitions incredibly smooth and compliant against internal walls, Bob highly recommends ordering this piece in our #00-50 (soft) compressible silicone. This plush composition allows the wide segments to compress under internal muscle pressure, ensuring a highly comfortable, low-fatigue stretching routine.

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.
