Nubby OF

Discover ultimate hands-free security and low-profile threshold fulfillment with the Nubby OF. Engineered specifically for users who demand a completely reliable anchor without deep internal reach, this compact silicone retention plug is a masterclass in high-leverage geometry. By pairing a prominent, heavy-set bulbous tip with an ultra-narrow structural neck, it allows your pelvic floor muscles to lock effortlessly over the core of the plug. Finished with an ergonomically contoured oval safety flange, the Nubby OF sits perfectly flush against the body, staying securely in place during long-duration wear.

High-Leverage Ball Tip & Oval Base: The architectural layout of the Nubby OF is optimized for maximum mechanical advantage right at the threshold. It guides placement with a beautifully rounded, 30mm maximum diameter ball tip that provides an immediate, satisfying sense of localized fullness. Immediately following this primary expansion, the profile drops sharply down to an ultra-slim 17mm diameter retention neck. This dramatic architectural reduction allows muscles to contract completely and effortlessly, creating an unyielding internal lock. The appliance terminates at a specialized oval retention flange that measures 28.5mm across its flat sides and expands to 41mm from end to end, ensuring a low-profile, pinch-free fit against the body.

Anatomical Design & Dimensions:

• Overall Length: An ultra-compact and discrete 53mm total length.

• Maximum Insertable Depth: Provides a stable, low-leverage 47mm of fully usable insertion length.

• Enlarged Ball Tip: Features a robust 30mm maximum expansion width by 25mm in length for intense, localized threshold fulfillment.

• High-Leverage Retention Neck: Narrows down sharply to a sleek 17mm diameter structural neck, allowing muscles to naturally anchor the plug hands-free without fatigue.

• Ergonomic Oval Flange: Expands to 27mm at the base transition, measuring 28.5mm from flat side to flat side and 41mm from rounded end to rounded end to eliminate twisting and rest flush against the body.

👑 Bob's Choice Recommendations

• Experience Level: Beginner. While its short profile is highly manageable, the rapid transition from a 30mm ball tip down to a 17mm neck provides a very distinct, high-security internal stretch that is perfect for users familiar with flanged retention plugs.

• The Prime Durometer Recommendation: For a short, high-leverage retention piece like the Nubby OF, Bob highly recommends ordering in our #10 (medium) composition. This density provides the absolute best structural feedback, ensuring the 30mm ball tip keeps its crisp shape and the narrow 17mm neck provides a firm, reliable anchor against muscular compression.

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.
