Review (4/5): files aren't 10/10 but the nail buffs are!
The grit isn't very strong on the nail rectabgle buffs and files, but on the buffers with all the different sides it's really strong and really good, just harder to file short nails with. That said, it was still able to file down acrylic nails it just took a little longer.
But I really like the buffer files with the different sides, my damaged nail from acrylics was easy to smooth down to paint over it. The brushes are nice and do their job well as well. And it comes with plenty so I know it will be awhile before I run out!
