I have been buffing my nails for several years now. In-between my manicures, I use a little block "sort of" similar to these. I say "sort of" because, frankly, there is no comparison! I got these, and I was a little intimidated about buying 6 at once. But I'll never use anything else! They're SO GREAT. They work so well, and the shine from them lasts well after buffing!
