Designed with a gradual stretch profile, it features a 7" total length (6" recommended insertion depth) that delivers deep, localized expansion and structured progression. Its shaft profile maintains an aggressive peak width bulge located precisely 1.25" from the tip, providing focused internal engagement before tapering into a narrow retention valley

Anatomical Sizing & Mechanics

  • Entry Tip: Smooth, tapered entry tip designed for precision, effortless alignment.

  • Shaft Progression: Rapidly expands to its peak diameter bulge at 1.25" from the tip before transitioning into a narrow retention valley.

  • Textural Details: Features 6 small underside bumps and 2 raised top nodules to engage multiple internal contact points along the canal pathway.

  • Safety Flange: Integrated, solid base flange (13mm–33mm) acts as a reliable docking limit for controlled, grounded use.

Anatomical Depth Guide The SSND-THING 7" features a total length of 7.0" (177.8mm) with a recommended insertable depth of 6.0" (152.4mm). This extended profile provides deep canal reach, placing tactile feedback and targeted expansion deep along the insertion pathway.

Bob's Choice Recommendations

  • Experience Level: Intermediate to Advanced (Sizing spans from 10mm up to a 25mm / 1" peak shaft bulge).

  • The Prime Durometer Recommendation: We strongly recommend #10 (medium) platinum silicone density. This formulation provides necessary structural rigidity to prevent unwanted flexing or bowing during insertion while delivering high-definition tactile transmission through the surface nodules and underside bumps.

  • The Alternative Durometer: Select #00-50 (soft) for a more pliable, forgiving insertion, or #18 where maximum firmness and unyielding stretch response are required.

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.
