The pink crystal on the flat base is genuinely pretty and doesn't dig in at all when sitting. The 2.6 cm diameter is a good sweet spot for me, and the rigid metal feels solid without being uncomfortable.

The spiral design makes insertion smoother than I expected, and the flat base sits comfortably without digging in. The pink crystal on the base is a nice touch too.

The metal has a nice weight to it that makes it feel secure, and the flat base with the pink crystal sits comfortably without digging in. At 2.6 cm it's a good size for regular use, not too intimidating but still substantial.
