The Knobby Jumbo is a large, full-length textured nozzle with a rounded 1.75" tip and a shaft covered with rounded bumps. The shaft stays approximately 1.75" in diameter from the tip through the textured section.

The bumps run along the full 10" insertable length. A wide safety flange at the base provides an external stop.

Shape

The Knobby Jumbo has a rounded, bulb-shaped tip followed by a straight, full-diameter shaft. Unlike a ribbed nozzle with large changes in diameter, this design keeps the main shaft at approximately 1.75" while adding a dense pattern of rounded bumps over the surface.

The base ends in a wide flange that acts as a safety stop.

Choosing your silicone firmness

For the Knobby Jumbo, Bob recommends #10 Medium for most users. The firmer silicone gives the long shaft enough structure to hold its shape during use while keeping the rounded bumps defined.

#00-50 Soft is also available if you prefer a more flexible piece. The softer material allows the shaft and bumps to flex more easily.

If you're unsure which firmness to choose, we can make firmness samples.

Color options

#18 and #30 are available in pure translucent silicone.

#00-50 and #10 use a translucent white base and can be mixed with standard colors.

Please note

The Knobby Jumbo is a large 1.75" diameter design with a 10" insertable length. It is intended for experienced users rather than beginners.

Anatomy varies, and no single size or shape will work for everyone. Use appropriate lubrication, never force the product, and stop if you experience pain or significant discomfort.

Inspect the silicone before each use. Do not use the product if it is damaged.
