SSND-RNDMBALL 9-12.5
Recommended for open bore options
Driven by the feedback and requests of our dedicated patrons, this premium platinum-cured silicone sound features an intricate multi-ball style shaft, an elegantly contoured tip, and a specialized hold-in-place anchor zone. Packed with 22 separate expanded ribbed areas that alternate dynamically in shape, length, and diameter, this probe delivers a shifting landscape of sensations as it traverses your anatomy.
Anatomical Sizing & Shifting Wave Mechanics:
-
The Elegantly Contoured Entry: Starts with a marginally tapered mini-ball style rounded tip measuring 9.5mm to initiate a smooth, non-binding introduction through the Meatus.
-
The Shifting 22-Node Column: Moves through a sequence of small spherical balls and gradually tapered barrels that swell and contract. The nodes climb from 11mm up to an intense 12.7mm peak expansion at the 15th rib zone, keeping the entire canal under a diverse, rolling volumetric stretch.
-
The Flanged Retention Lock: The 22nd and final ball tapers to 12mm to provide a final gentle stretching action, dropping sharply into a 9mm retention valley positioned directly ahead of the safety flange to let the primary sphincter muscle close tightly around the groove, anchoring this extra-long sound securely in place.
Anatomical Depth Guide: Featuring an incredible 16.5-inch (419mm) total insertable length up to the flanged base, this sound offers total depth control. It effortlessly lines the anterior pendulous tract, navigates the bulbar curve, passes the pelvic floor, and completely bridges the prostatic canal to rest deeply within the inner cavity for an all-encompassing experience.

👑 Bob's Choice Recommendations
-
Experience Level: Intermediate. Because of its 16.5" total depth and heavy-volume 12.7mm nodes, this custom multi-ball probe is recommended for experienced intermediate and advanced users who have fully mastered full-length deep-tract play.
-
The Prime Durometer Recommendation: To make this extensive, 22-node layout remarkably giving and low-fatigue across its entire length, Bob highly recommends ordering this piece in our #10 (medium) or #00-50 (soft).
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.
