Recommended for open bore options

SSND-CNTRD3 is a compact 3" insertable silicone sound featuring a streamlined, contoured node profile engineered for smooth retention and localized sensation. Similar to our short catheter designs, this model replaces sharp texturing with a series of smooth, flowing swells and valleys. It begins with a 7mm (21 Fr) tapered entry tip that expands gradually to a 9.5mm (28 Fr) swell before relaxing back into a 7mm valley. This alternating contoured profile repeats along the shaft until it reaches an 8mm (24 Fr) retention valley directly in front of the smooth ball flange base. Available in solid-core or open-core configurations, the hollow option allows for natural fluid passage during wear.

Anatomical Sizing & Mechanics

Tapered Entry Tip: Starts with a smooth 7mm (21 Fr) taper for comfortable, effortless entry past the meatus.
Flowing Contour Swells: Tapers up to 9.5mm (28 Fr) alternating swells separated by 7mm valleys to provide gentle, rhythmic surface contact.
Smooth Retention Body: Omits outer ribbed texturing in favor of continuous, smooth transitions for low-friction placement and removal.
Proximal Retention Base: Drops into an 8mm (24 Fr) retention valley directly before the ball flange to comfortably hold position near the entrance.

Anatomical Depth Guide

Providing 3" (76mm) of insertable depth, the SSND-CNTRD3 provides targeted reach within the navicular fossa and distal pendulous urethra. It delivers localized volumetric presence and subtle retention near the entrance without deep anatomical expansion.

👑 Bob's Choice Recommendations

Experience Level: Beginner
The Prime Durometer Recommendation: #10 (Medium) For a compact 3" contoured sound, #10 offers the ideal balance of soft tissue compliance and sufficient column stability for easy placement.
The Alternative Durometer: Consider #00-50 (Soft) for ultra-gentle, cushioned wear during extended placement or #18 (Firm) for added firmness during handling.

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.
