Whether you are looking for introductory sensation or advanced, deep-pathway exploration, the SSND-7mm is designed to provide consistent, smooth feedback. With available lengths of 8", 12", and 18", this piece scales perfectly from novice stretching to deeper, more involved engagement.

At 7mm (21.2 French), this piece is slender enough to navigate the sensitive anatomy of the penile urethra comfortably, yet significant enough to provide a noticeable, firm presence. When inserted, the rounded tip navigates past the meatus with ease, allowing for controlled transit through the spongy urethra and, at longer lengths, reaching toward the prostatic urethra and bladder neck.

Technical Specifications

  • Diameter: 7mm (0.275") | 21.2 French

  • Available Lengths: 8", 12", 18" (Insertable length to base flange) The 8" option is excellent for focused, internal play, while the 12" and 18" options provide the length necessary to comfortably reach the bladder neck and internal sphincter.


👑 Bob's Choice Recommendations

Expert Recommendation Beginner - Intermediate: For those new to the sensation, the 8" length offers a manageable, controlled experience. For those ready for more advanced, full-pathway depth, the 18" provides the reach you need. Pro-tip: If ordering solid, go with #18 firmness; if choosing the open-core for drainage, we recommend #30 firmness for better structural integrity.

Color Options: #18 and #30 are available in pure translucent. #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 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.
