Model O
Recommended for open bore options
The Model O is the longer, extended-reach version of our signature baseball bat styled nozzles. Engineered for advanced users who require extra length combined with classic tapered geometry, this sleek appliance mirrors the smooth, progressive flare of a traditional bat. The dynamic variation between its distinct oval tip and narrow mid-shaft creates an exceptionally smooth transition during use, providing a highly satisfying sense of internal fulfillment.
Ergonomic Taper & Fluid Control
-
Extended Oval Tip: Starts with a smooth, broad 1.4" (35.6mm) diameter tip section designed to gently open and navigate internal pathways.
-
Slender Transition Shaft: Tapers down smoothly right after the tip to a highly flexible 0.85" (21.6mm) diameter shaft that extends for 6.0" (152.4mm) in length. This slender middle zone allows pelvic muscles to rest comfortably without over-stretching during deep sessions.
-
Progressive Flare Base: Sweeps beautifully back outward from the narrow shaft to a substantial 1 7/8" (47.6mm) expanded base, serving as a highly effective, natural muscle stop and reliable hydraulic seal to minimize fluid backflow.

👑 Bob's Choice Recommendations
-
Experience Level: Intermediate. With a 16.0" total length and a 1.4" entry tip, the Model O is designed for enthusiasts looking to move up to extended deeper appliances.
-
The Prime Durometer Recommendation: #10 (Medium). This durometer gives the extended 16" body the essential column strength it needs to guide past internal resistance cleanly without looping or buckling, while maintaining perfect, flexible compliance with your natural anatomy.
-
The Ultra-Flexible Alternative: If you want this long baseball bat profile to feel incredibly plush, highly compressible, and effortlessly pliable throughout its entire 15" insertable length, Bob suggests selecting our extra-soft #00-50 composition.
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.
