The DBLBL (Double Ball) is a colon nozzle with a bulbous entry tip and a second retention ball near the base, joined by a smooth mid-shaft. It's the original piece in this line.

Details

• Overall length: 9.0" (22.9 cm)
• Insertable depth: 8.5" (21.6 cm)
• Bulbous entry tip: 1.4" (3.6 cm)
• Central shaft: 1.0625" (2.7 cm) diameter x 4.5" (11.4 cm) long
• Retention ball: 1.5" (3.8 cm)
• Retention valley: 1.0" (2.5 cm) long x 0.85" (2.2 cm) diameter

How it works

The rounded 1.4" bulb tip eases past the initial muscle group, then the shaft settles into a smooth 1.0625"-diameter section for 4.5" — giving the muscles a place to rest before the next expansion. Near the base, the shaft swells to a 1.5" retention ball, then narrows into a 1.0" long, 0.85"-diameter valley where the surrounding muscle locks around it, right up against the flared base flange.

Who it's for

This is a beginner-friendly piece — a stable, hands-free lock without the thickness or intensity of the larger sizes below.

Choosing your firmness

Bob recommends #10 (Medium) for this size — it gives the 0.85" retention neck a firm, reliable anchor against muscular compression.

If you're unsure which firmness to choose, we recommend ordering our silicone firmness samples first.

Color options

#18 and #30 are available in pure translucent.
#00-50 and #10 are translucent white base materials and can be mixed with standard colors.

Please note

Everyone's anatomy is different, and we cannot guarantee that a particular size or configuration will be suitable for everyone.
Use appropriate lubrication, never force the product, and stop if you experience pain or significant discomfort. Inspect the silicone before each use and do not use it if damaged.
