The RTDL 1.3 is a compact, 4.5" dilator with two separate expansion-and-valley stages, built for progressive stretching in a short, manageable length.

Details

• Total length: 4.5" (11.4 cm)
• Insertable length: 4.0" (10.2 cm)
• Tapering tip diameter: 1.3" (3.3 cm)
• First retention valley: 1.0" (2.5 cm)
• Expansion bulb diameter: 1.1" (2.8 cm)
• Base retention valley: 0.9" (2.3 cm)
• Base flange diameter: 1.75" (4.4 cm)

How it works

The tapering tip widens to a 1.3" maximum diameter, then narrows into a 1.0" valley where the muscle can anchor for the first time. For deeper placement, the shaft swells again to a 1.1" expansion bulb before narrowing into a second, 0.9" valley right against the 1.75" base flange — giving you two separate thresholds to work with instead of one.

Who it's for

This is a short-format training tool for users who want to practice accommodating width and multi-stage retention without the length of a full-sized colon tube.

Choosing your firmness

Bob recommends #10 (Medium) — enough definition to hold the dual-valley shape without being too firm.

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.
