Black silicone Knobby Jumbo nozzle with textured surface, 1.75 inch diameter, and safety flange on a grid background

2 Black silicone Knobby Jumbo nozzle with textured surface, 1.75 inch diameter, and safety flange on a white background

This great nozzle has so many possibilities I don't know where to begin. Needless to say, it is a multifunctional piece. Nice, rounded tip for gentle entrance followed by an array of soft little bumps covering the remainder of the shaft out to the safety retention flange. This piece can be used as a nozzle, a massage piece, a plug and can even be mounted into a harness if you like.

This one measures in with a bulbous 1 3/4" tip diameter followed by the same size shaft with all those delightful little bumps. The 10" length is completely insertable and will definitely get your attention. This nozzle is really quite comfortable and functional.

👑 Bob's Choice Recommendations

Advanced Volume & Length: With a substantial 1.74" shaft diameter and a full 10" of completely insertable length, the Knobby Jumbo is an impressive, high-capacity piece. Bob notes that this model provides a highly commanding internal presence and is recommended for experienced intermediate users rather than beginners.
The Prime Durometer Recommendation: For a textured, multi-functional design of this size, Bob highly recommends selecting #10 firmness. This material density provides the ideal amount of structural integrity to keep the shaft from collapsing during placement—especially if you plan to mount it into a harness—while keeping the array of knobby surface bumps beautifully pronounced and effective.
The Extra-Flexibility Alternative: If you plan to use this piece strictly as a long-duration retention plug or prefer a highly pliable, yielding feel that effortlessly molds to your body's natural contours under muscle pressure, Bob suggests choosing our soft #00-50 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.

Important Safety Disclaimer: Because individual anatomy varies, we cannot guarantee a full fit for all 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.
