SSND-Diamond 8-25 BF is a diamond-profile silicone extra wide sound and plug featuring our signature ball flange base design. Engineered for high-capacity volumetric stretching, this model pairs an elongated diamond expansion profile with a secure, ergonomic base. It provides approximately 3.75" of insertable depth, beginning with a soft rounded 8mm (24 Fr) entry tip that tapers smoothly up to a powerful 24.7mm (74.1Fr) maximum diameter mid-shaft swell. Behind the peak expansion, the shaft relaxes into a 17mm (51 Fr) retention valley before terminating at a prominent 1.3" (34mm) ball flange. Available in solid-core or open-core configurations, the hollow option allows for natural fluid passage during wear.

Anatomical Sizing & Mechanics

• Soft Rounded Tip: Starts with an 8mm (24 Fr) entry tip designed for smooth, gradual entry past the meatus.

• Aggressive Mid-Shaft Swell: Expands along a 3.75" (95mm)" insertable run to a maximum 24.7mm (74.1Fr) diameter for maximum volumetric tissue stretching.

• Deep Retention Valley: Slopes back down to a 17mm (51 Fr) neck to allow tissue to settle comfortably behind the main body.

• Ergonomic Ball Flange Base: Features a 1.3" (34mm) rounded ball flange to provide superior handling control and prevent over-insertion.

Anatomical Depth Guide

Providing approximately 3.75" (95mm) of insertable depth and 4.75" (120.5mm) of total length, the SSND-Diamond 8-25 BF delivers substantial expansion within the navicular fossa and pendulous urethra. It is built specifically for users focused on high-diameter stretch near the entrance rather than deep-channel penetration.

Dimension & Sizing Profile

👑 Bob's Choice Recommendations

• Experience Level: Advanced

• The Prime Durometer Recommendation: #10 (Medium) is the primary recommendation for this model. Given the large 24.7mm (74.1Fr) body profile across a 4" insertable shaft, #10 offers optimal structural body support while maintaining the pliability needed for smooth placement.

• The Alternative Durometer: Consider #00-50 (Soft) for users seeking extra tissue compliance and cushioned flexibility during extreme stretching, or #18 (Firm) for added firmness and precise 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.
