SSND-5.5mm
Recommended for open bore options
SSND-5.5mm is an ultra-slender 15" solid-core silicone sound engineered for smooth navigation and precise depth exploration. Serving as the next size step in our micro-diameter series, this model features a uniform 5.5mm (16 Fr) profile paired with a smooth, rounded entry tip. Its ultra-smooth surface texture is designed to retain microscopic beads of lubricant along the shaft, enhancing glide and internal sensation during movement. Because of its slender 5.5mm cross-section, this piece is available exclusively in a solid-core configuration to ensure ideal column strength and handling.
Anatomical Sizing & Mechanics
-
Smooth Entry Tip: Features a seamlessly rounded head engineered to pass comfortably past the meatus with minimal initial resistance.
-
Uniform 5.5mm Cross-Section: Maintains a continuous 5.5mm (16 Fr) diameter across the full length for smooth, constant feedback without wide expansion points.
-
Micro-Lubricant Surface: Designed to hold microscopic beads of lubricant along the body to maintain smooth glide during long-pathway navigation.
-
Solid-Core Construction: Offered exclusively in solid silicone to maintain structural column stability across its extended length.
Anatomical Depth Guide
With an extended 15" (381mm) total length, the SSND-5.5mm provides deep anatomical reach. At a slender 5.5mm (16 Fr) diameter, it navigates past the pendulous and bulbar urethra, advancing through the prostatic urethra and internal sphincter toward the bladder neck for full-pathway exploration.

👑 Bob's Choice Recommendations
-
Experience Level: Beginner (due to 5.5mm slender diameter but it is pretty long at 15")
-
The Prime Durometer Recommendation: #18 (Firm) is the primary recommendation for this model. Given the ultra-slender 5.5mm diameter across an extended 15" shaft, #18 provides essential column rigidity to prevent excessive bending and ensure smooth, controlled insertion.
-
The Alternative Durometer: Consider #30 (Very Firm) for users seeking maximum pushability and tactile control at deep anatomical depth.
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.
