Hegar Sound - 9 to 10 mm

Finally, a chance to buy just one of these instead of a whole set — perfect for someone like me who only needed a specific size. The slightly different ends make it more versatile than I expected for gradual use.

The two ends being slightly different diameters makes it easy to step up gently without needing a whole set, and the single purchase is perfect for just trying one. It's smooth and solid, exactly what I needed for a quick test before committing to more.

Bought a single one to test the waters and the smooth finish makes insertion far more comfortable than I expected. The dual diameters are a nice touch for gradually working up, and it's held up well to repeated cleaning.
