Model M
Recommended for open bore options
The Model M is a sloped oval-tip nozzle available in three progressive sizes in one listing — 1.2" (Classic), 1.85", and 2.1" — sharing the same shaft length and shape.
Details (shared across all sizes)
- Overall length: 5.0" (12.7 cm)
- Insertable depth: 4.5" (11.4 cm)
- Mid-shaft length: 2.5" (6.4 cm)
Size-specific dimensions
| Size | Tip (max diameter) | Neck (min diameter) | Flange diameter |
|---|---|---|---|
| 1.2" Classic | 1.2" (3.0 cm) | 0.6" (1.5 cm) | 1.3" (3.3 cm) |
| 1.85" | 1.85" (4.7 cm) | 0.95" (2.4 cm) | 2.2" (5.6 cm) |
| 2.1" | 2.1" (5.3 cm) | 1.1" (2.8 cm) | 2.5" (6.4 cm) |
How it works
Across all three sizes, the sloped oval tip guides entry, then the shaft settles into a smooth 2.5" section before reaching the flared base flange — the same shape just scaled up, so the feel is consistent as you move between sizes.
Who it's for
This line is a progressive range, from the 1.2" Classic for beginners up through the 2.1" for more experienced users, so you can step up within the same design as you go.
Choosing your firmness
Bob recommends #10 (Medium) for the 1.2" Classic. For the 1.85" and 2.1" sizes, which carry more material mass, #00-50 (Soft) keeps the larger tip comfortable and compressible on entry.
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.
