These fit the 3.1mm small mandrel perfectly with no wobble, which was my main worry. The medium grit takes off gel without chewing up the natural nail underneath. I've already gone through about ten doing fills and haven't hit a single dud.

Finally, a sanding band that actually fits my 3.1mm mandrel perfectly. The medium grit takes down acrylic smoothly without clogging or skipping.

The medium grit is perfect for cleaning up gel around the cuticle without eating into the nail plate. I've been through about ten of them this month and they haven't lost their bite yet. Wish the pack had a few more fine ones mixed in, but for the price it's hard to complain.
