Disappointed [SEP] I bought it because of a hard case. But my old glass nail file which I have more than two years works better than this one. I started my manicure with this one and finished with my old nail which I thought was wour out (before, now I think it's not bad at all lol) This nail file is really slow and uncomfortable to use, it's like an old knife that can't cut anything. I like the hard case but it doesn't matter since file not good. Two Stars for hard case. Probably if you never used high quality nail glass before you will like it
