OF 1

The OF 1 is our smaller-sized oval flange-styled nozzle, it blends high-performance fluid retention with low-profile anatomical comfort. The defining feature of this model is its specialized oval base, which is deeply contoured to fit flush against the gluteal cleft of the body. This design provides an incredibly secure, low-pressure fit and an easy grip, making it an exceptional choice for standard enema routines, extended wear, or hands-free retention training.

Moving past the entry tip, the shaft swells into a smooth, gradual bulb that creates a highly effective natural muscle block. This architecture seals fluid backflow effortlessly, allowing for a comfortable and leak-free cleansing experience.

Anatomical Design & Dimensions:

• Overall Length: A compact 4.7” total length.

• Insertable Depth: Provides 3.75” of fully insertable length.

• Tapered Shaft: Starts with a smooth rounded tip that steps to 1.0” (25.4mm) before expanding to an approximate 1.6” (40.6mm) maximum diameter swell.

• Retention Valley: Tapers back down to a narrow 0.8” (20.3mm) diameter neck to eliminate localized pressure on the sphincter muscle.

• Anatomical Oval Flange: Measures approximately 1.1” thick by 2.2” wide at the base to prevent over-insertion and rest comfortably against external contours.

👑 Bob's Choice Recommendations

• Experience Level: Advanced Beginner / Intermediate. Thanks to its shorter 3.75" insertable length and highly supportive oval base, the OF 1 serves as an approachable, highly functional entry point for users exploring dedicated retention shapes.

• The Prime Durometer Recommendation: For an optimal balance of structural retention and plush comfort, Bob highly recommends ordering the OF 1 in #10. This density allows the 1.6" maximum bulb to maintain its leak-preventing shape perfectly while yielding easily to your body's natural movements.
  

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.
