From our R&D workshop, the SSND-MIXRIB stands out as a unique and highly popular addition to our advanced texturing lineup. Moving past traditional uniform shafts, this premium platinum-cured silicone sound utilizes an array of shifting rib configurations that alternate dynamically along its compact length. Its striking, stylized silhouette evokes the look of an elegant chess piece, combining aesthetic artistry with practical physical mechanics to deliver a highly stimulating, mixed-pressure internal stretch.

Anatomical Sizing & Mixed Rib Mechanics:

Calibrated to keep internal tissue actively engaged through alternating structural textures, the architecture of this sound is divided into distinct tactile zones:

  • The Ornate Entry Tip: Begins with a smooth, beautifully contoured tapered tip that allows for a predictable and controlled initial introduction.

  • The Quad-Rib Array: The first major tracking section features four tightly packed, narrow ribs that create a rapid-fire ripple sensation as the probe moves through the opening.

  • The Extended Barrel Swell: The center of the shaft transitions into a long, smooth, sweeping barrel expansion that gently pushes the walls out to its maximum 13mm to 14mm diameter range.

  • The Triple Ring Lock: Following the main swell, the shaft steps into three broader, heavy-set expansion bands separated by distinct valleys. This high-definition sequence leads to a final structural groove, allowing the entry sphincter muscle to seat itself securely just ahead of the integrated safety base flange.

Anatomical Depth Guide:

Designed with a convenient 5-inch overall length providing approximately 4.5 inches (114mm) of recommended insertable depth, this model is perfectly scaled for low-fatigue, concentrated training. The short-stature profile ensures that the substantial 14mm expansion zones remain focused directly within the highly sensitive pendulous and lower canal tract without requiring deep pelvic floor navigation.

Dimension & Sizing Profile

The precise structural breakdown of the MIXRIB architecture is calibrated as follows:

Feature / Zone Millimeters (mm) Functional Profile & Texture
Introduction Tip Tapered Entry Smooth initial calibration point
Primary Texturing 13.0mm – 14.0mm Range Four rapid-fire, closely stacked structural ribs
Mid-Shaft Swell 14.0mm Maximum Peak Long, fluidly rounded barrel expansion
Secondary Texturing 13.0mm – 14.0mm Range Three broad, heavy-set stabilization rings
Retention Seat Narrow Valley Anchoring groove for secure hold-in-place seating
Safety Stop Integrated Base Flange Wide flared base to prevent migration

👑 Bob's Choice Recommendations

  • Experience Level: Intermediate. Ideal for practitioners who are fully comfortable with standard mid-tier gauges and are ready to experience a robust 14mm volumetric stretch using a shorter, low-fatigue insertable length.

  • The Prime Durometer Recommendation: To make the diverse structural textures and the 14mm barrel swell exceptionally smooth and compliant against internal walls, Bob highly recommends ordering this piece in our#10 (medium) silicone. 

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.
