The RTDL 2.25"–3.0" is the larger-size version of the RTDL series. It uses the same basic design as the smaller models: a rounded expansion head, a smaller straight shaft, and a wide external flange.

Choosing your silicone firmness

For the 2.25" (5.72 cm) and 2.5" (6.35 cm) sizes, Bob recommends #00-50 Soft.

For the 2.75" (6.99 cm) and 3.0" (7.62 cm) sizes, Bob recommends #00-20 Very Soft.

The softer materials allow the larger expansion heads to flex more easily. Firmer silicone is available if you prefer more structure.

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

Color options

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

#00-20, #00-50, and #10 use a translucent white base and can be mixed with standard colors.

Please note

These are large-diameter designs intended for experienced users. Size and silicone firmness both affect how the piece behaves.

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.
