OF 13

The OF 13 stands as our most impressive, large-scale nozzle, meticulously engineered for advanced users who demand the ultimate in internal volume, deep-reach capacity, and uncompromising structural presence. This magnificent model features three beautifully contoured entry ribs that transition into a massive 2.5" primary retention ball, delivering an extraordinary sense of internal fulfillment and secure, heavy-duty fluid management.

Anatomical Gluteal Flange & High-Capacity Lock: To provide maximum control over its large profile, the OF 13 is equipped with our signature oval retention flange. This shape-conscious base is specifically contoured to sit flush against the gluteal cleft of the body for superior comfort and a remarkably low-profile fit. When fully inserted, the pelvic floor muscles rest securely behind the heavy 2.5" retention ball, creating an absolute hands-free hydraulic seal that locks large volumes of enema solution in place without leaking.

Anatomical Design & Dimensions:

• Overall Length: A commanding 13.5” total length.

• Insertable Depth: Provides a deep, fully usable 10.5” insertable length up to the base flange.

• Smooth Tapered Tip: Starts at an ultra-accessible 0.5” diameter tip before gently tapering up to 1.3” ahead of the first internal valley.

• Contoured Ribbed Shaft: Features three distinct, smooth internal ribs measuring approximately 1.4” in diameter for exceptional tactile stimulation.

• Massive Retention Ball: Sweeps dramatically upward to a heavy-gauge 2.5” diameter retention ball for maximum muscular anchorage.

• Oversized Gluteal Flange: Finished with a robust oval base flange measuring approximately 2” thick by 4” wide, acting as a secure handling grip and reliable external safety stop.

👑 Bob's Choice Recommendations

• Experience Level: Advanced: With a 10.5" insertable reach and a substantial 2.5" maximum expansion ball, the OF 13 is tailored strictly for experienced size enthusiasts.

• The Prime Durometer Recommendation: For a heavy-capacity, multi-ribbed model like this, Bob highly recommends ordering in #00-50 (soft). Because a 2.5" solid sphere carries a significant amount of material mass, selecting our #00-50 composition ensures the large retention ball and structural ribs feel incredibly plush, forgiving, and compressible during entry, allowing the piece to conform beautifully to your natural internal anatomy under pressure.

• The Maximum Structural Alternative: If you are a veteran user who wants this thick, ribbed profile to feel completely unyielding, solid, and maintain its intense, heavy presence under maximum muscle compression, Bob suggests selecting our #10 (medium) composition.

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.
