OF 1.3

Discover an exceptional balance of sleek, low-resistance wearability and high-efficiency fluid containment with the OF 1.3. Positioned as a versatile intermediate model within our premier oval flange design series, this 6.75-inch premium silicone appliance is engineered specifically to support optimal, long-duration retention. Featuring a gently contoured, progressive swell along the main shaft that drops into a dramatic architectural reduction, the OF 1.3 provides a remarkably secure and comfortable hands-free fit when utilized as a dedicated retention-style enema nozzle, douche, or lifestyle trainer.

Progressive Shaft Swell & Anti-Rotation Oval Base: The layout of the OF 1.3 is sculpted to maximize mechanical retention right at the threshold while keeping internal reach highly manageable. It guides placement with a beautifully rounded 1.0-inch tip that gradually expands over the shaft to a maximum diameter swell of 1.3 inches, delivering a satisfying but highly approachable sense of localized fullness. Immediately after this primary swell, the profile tapers smoothly down into a tight 0.75-inch diameter retention neck. This dramatic reduction allows your pelvic floor muscles to contract completely and effortlessly over the core of the plug, locking it hands-free against an ergonomically contoured oval flange base measuring 1.5 inches by 4.0 inches wide. This wide, low-profile base rests perfectly flush within body contours, preventing uncomfortable rotation and forming an absolute fluid-tight hydraulic seal.

Anatomical Design & Dimensions:

• Overall Length: A balanced and versatile 6.75” total length.

• Insertable Depth: Provides a stable, low-leverage 6.0” of fully usable insertion length.

• Sleek Shaft Profile: Starts with a comfortable 1.0” rounded tip and graduates seamlessly to a maximum diameter swell of 1.3” for a smooth internal presence.

• High-Leverage Retention Valley: Tapers down sharply behind the main swell to a tight 0.75” diameter neck, letting sphincter muscles lock the plug in place hands-free without fatigue.

• Ergonomic Oval Flange Base: Finishes with an anatomically contoured 1.5” by 4.0” wide safety flange that eliminates twisting, sits flush against the body, and acts as a dependable fluid barrier.

👑 Bob's Choice Recommendations

• Experience Level: Intermediate. An excellent step up for rising users who have mastered introductory sizes and want to experience a highly secure, hands-free threshold lock paired with a low-profile, anti-rotation base.

• The Prime Durometer Recommendation: For an intermediate, high-retention piece like the OF 1.3, Bob highly recommends ordering in our #10 (medium) composition. This density provides the absolute best structural definition, ensuring the 1.3-inch shaft swell keeps its crisp shape, and the narrow 0.75-inch neck provides a firm, highly 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.
