SSND-MLTIDML 8-12
Recommended for open bore options
The SSND-MLTIDML 8-12, a unique multi-dimensional flexible sound designed for dynamic internal stimulation. Moving away from traditional single-diameter shafts, this premium platinum-cured silicone sound utilizes a layout that continuously shifts in diameter. By combining tightly segmented entry nodes with an extended mid-shaft tracking zone and a heavy final barrel, this probe delivers an incredibly comfortable, yet highly stimulating experience tailored for extended wear.
Anatomical Sizing & Multi-Stage Progression Mechanics:
The complex structural blueprint of this sound is carefully stepped to allow your anatomy to adapt progressively as the probe slides deeper into the canal:
-
The Segmented Entry: Features a smooth, rounded tip starting at an approachable 7mm that immediately steps up through rapid, groove-separated segments measuring 8.5mm, 9mm, and 9.5mm to initiate a controlled initial expansion.
-
The Primary Wave Transitions: Past the entry rings, the shaft swells to a 10mm ridge before dropping back slightly to a 9.3mm relief zone. It then climbs smoothly to an 11mm expansion before settling into an extended 3.5-inch long tracking section calibrated at 10mm and detailed with three small pressure-relieving grooves.
-
The Final Barrel & Retention Lock: Following the main tracking shaft, the sound steps up to 10.5mm for an inch before widening into a substantial 12mm barrel to deliver a deep, satisfying peak stretch. The profile then tapers down immediately into a narrow 9.5mm retention valley, allowing the entry sphincter muscle to seat itself securely just ahead of the expanded safety base flange to prevent any unwanted migration.
Anatomical Depth Guide:
Offering approximately 8 inches (200mm) of total insertable length up to the flanged base, this flexible sound is perfectly sized to engage the full pendulous tract and sit comfortably within the bulbar curve. The 8" depth ensures complete control during extended-wear sessions, maintaining a steady, low-fatigue stretch along the primary muscle groups.
Dimension & Sizing Profile
The precise architectural breakdown of the MLTIDML 8-12 column is calibrated as follows:
| Structural Zone / Feature | Diameter (mm) | Functional Profile & Texture |
| Rounded Introduction Tip | 7.0mm | Smooth initial entry point |
| Graduated Entry Segments | 8.5mm ➔ 9.0mm ➔ 9.5mm | Rapid-fire micro-nodes separated by small grooves |
| First Wave Expansion | 10.0mm (Drops to 9.3mm) | Secondary muscular staging ridge |
| Main Tracking Shaft | 11.0mm ➔ 10.0mm | 3.5-inch extended zone featuring 3 accent grooves |
| Pre-Barrel Step | 10.5mm | 1-inch long preparatory ramp |
| Peak Stretch Barrel | 12.0mm | Maximum diameter segment for full tissue engagement |
| Retention Lock Valley | 9.5mm | Narrow groove for secure hold-in-place sphincter seating |
| Safety Base Flange | Expanded Flange | Wide anti-migration stop |
👑 Bob's Choice Recommendations
-
Experience Level: Intermediate. Excellent for practitioners who want to advance into 11mm to 12mm volumes using a highly compliant, multi-stage layout that avoids the sudden friction of a standard straight shaft.
-
The Prime Durometer Recommendation: For an incredibly luxurious extended wear routine, Bob highly recommends 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.
