SSND-CNTRD13
Recommended for open bore options
SSND-CNTRD13 is an extended 13" insertable silicone sound featuring our signature contoured multi-ring tip paired with a dual-retention system. Designed specifically to anchor comfortably within internal sphincters for extended wear, it starts with a semi-rounded, four-sided flattened entry tip that provides unique textural variation during movement. The forward shaft features a series of precise sensory expansions and valleys—dipping from a 7mm tip down to 6.5mm, stepping up to 7.6mm, dropping into a 6mm prostate anchor valley, and reaching a 8mm maximum diameter body. The smooth 8mm shaft extends full length to a final 6mm retention valley positioned directly proximal to the flared safety base. Available in solid-core or open-core options, the hollow configuration supports natural fluid drainage.
Anatomical Sizing & Mechanics
-
Four-Sided Contoured Tip: Features a semi-rounded entry head with four flattened, polished sides that deliver distinct rotational feedback during insertion.
-
Prostate-Anchoring Valleys: Integrates alternating sensory expansions (7.6mm / 22.8 Fr) and relief grooves (6.0mm / 18 Fr) designed to let internal sphincters settle naturally into place.
-
Continuous 8mm Shaft: Expands to an 8mm (24 Fr) main body that maintains uniform diameter across the full length of the insertion path.
-
Proximal Retention Base: Features a secondary 6mm (18 Fr) valley right in front of the flared safety flange, allowing the meatal sphincter to capture the sound securely during wear.
Anatomical Depth Guide
With a 13" (330mm) insertable length, the SSND-CNTRD13 provides deep-reach insertion suited for full-length sounding. Combined with a slim 8mm (24 Fr) maximum diameter and multi-groove anchor system, it balances extensive internal reach with light, manageable volume.

👑 Bob's Choice Recommendations
-
Experience Level: Intermediate
-
The Prime Durometer Recommendation: #10 (Medium) is the primary recommendation for this model. Given the extended 13" insertable shaft with a slim 8mm body, #10 supplies essential structural column strength for easy depth navigation while remaining flexible enough to conform to internal contours.
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.
