Stretch more with your sounding routine with the SSND-RNDMBALL 11-14mm, the ultimate heavyweight expansion tool in our premium collection. Built directly in response to our respected patrons returning for deeper, larger-diameter profiles, this elite platinum-cured silicone sound blends full-length deep-canal immersion with a shifting, undulating landscape. Featuring 22 separate expanded ribbed areas that graduate in diameter, shape, and length, this probe delivers an incredibly intense, rolling stretch that completely satisfies heavy-volume calibration goals.

Anatomical Sizing & Heavy-Volume Node Mechanics: The Broad Conical Entry: Introduces a marginally tapered tip starting at an already substantial 11mm (33 French) to ensure a smooth, non-binding initial introduction.

  • The 22-Node Heavy-Volume Column: Progresses rapidly through an alternating series of distinct spherical nodes and gradually tapered barrels. The architecture swells past 12.5mm and 13mm, reaching 14mm (42 French) maximum peak at multiple intervals (including the 6th, 12th, 13th, 15th, and 16th segments), maintaining an extreme, all-encompassing muscular stretch.

  • The Flanged Retention Lock: The 22nd and final ball tapers down to 12.8mm (38.5 French) to provide a gentle, final relaxation step. This transitions immediately into a deep 9mm retention valley situated directly ahead of the safety flange to let the primary entry sphincter muscle close naturally around the groove, anchoring this massive sound securely in place to create a perfect fit.

Anatomical Depth Guide: Boasting a comprehensive 16.5-inch (419mm) insertable length up to the flanged base (17 inches total length). It seamlessly bridges the entire tract, traversing the anterior canal, navigating past the deep bulbar bend, and effortlessly clearing the prostatic sphincter to line the deepest internal pathways for an uncompromised experience.

👑 Bob's Choice Recommendations

  • Experience Level: Advanced. Due to its 14mm peak nodes and extensive 16.5" insertable length, this tool was intended for expert users who can safely accommodate high-volume deep-canal sounding.

  • The Prime Durometer Recommendation: To make these massive 14mm (42 French) dimensions comfortably approachable, Bob highly recommends ordering this piece in our plush #00-50 (soft) compressible silicone. This highly giving material formulation allows the large spheres to yield under tight muscle walls, minimizing fatigue and providing a remarkably smooth deep-capacity 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.

Important Safety Disclaimer: Because individual anatomy varies, we cannot guarantee a full fit for all longer or larger diameter pieces. Please use all products with care. By purchasing, you accept full responsibility for safe use. If you experience discomfort, discontinue use immediately.
