SSND-The Rod 12.5mm 12"-20"
Recommended for open bore options
For those who prefer a straightforward uniform 12.5mm (37.5 French) diameter profile, free from distracting ridges, ribs, or sudden transitions, this ultra-smooth instrument provides a highly predictable, simple-to-use, and comfortable experience. Available in three extended length configurations—12 inches, 16 inches, and 20 inches—The Rod is engineered for deep devotion, steady tracking, and full-length structural expansion.
Anatomical Mapping & Uniform Caliber Mechanics: The architectural layout of The Rod is sculpted to deliver an unchanging, steady level of internal pressure along the entire path of the canal:
-
The Entry: Begins with a perfectly smooth, rounded tip that establishes the full 12.5mm diameter right at the Meatus, initiating a complete, immediate wide-gauge calibration.
-
Continuous Expansion: As the sound slides inward, the uniform 12.5mm shaft maintains an identical, uninterrupted stretch along the full length of the Spongy (Penile) Urethra, offering constant, high-volume internal contact.
-
Deep Sphincter Passage: Without any relief valleys to pause in, the steady column demands relaxation as it passes through the narrow, less flexible Membranous Urethra.
-
Prostatic Seating & Beyond: The sound glides effortlessly into the spacious Prostatic Urethra. For users selecting the extended 16-inch or ultra-deep 20-inch lengths, the smooth body tracks past the Verumontanum and through the final Bladder Neck to achieve profound, full-canalled depth.
Anatomical Design & Shared Dimensions:
-
Insertable Length Options: Available in three distinct high-capacity lengths: 12 inches, 16 inches, or a maximum 20 inches of insertable depth.
-
Constant Diameter: Measures a substantial 12.5mm (37.5 French) from just behind the rounded tip down to the base stop.
-
Safety Flange Base: Finished with an integrated low-profile end stop flange to ensure absolute external safety and control.
👑 Bob's Choice Recommendations
-
Experience Level: Advanced. Because this model features a continuous 12.5mm wide-body diameter and stretches well past 8 inches in all configurations, it is classified as an advanced-level training sound.
-
The Prime Durometer Recommendation: Bob highly recommends ordering this model in our #10 (medium) material composition. This density strikes the ultimate balance for a long, uniform cylinder; it provides enough structural column integrity to make deep tracking simple and predictable
-
The Plush Alternative: If you want this thick, long profile to feel more yielding and compressible under internal muscle pressure, Bob suggests selecting our extra-soft #00-50 (soft) material option.
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.
