Since I had enough of metal nail files, it should even be something special. Files of ceramics are said not only hone better, but be practically wear-free. At first I was really excited. The joy did not last long. After about 2 months, both the coarse and the fine side scuffed. Then I contacted the manufacturer via this website. No Answer. A real shame. My purchase was a year ago, perhaps the production conditions have now been changed. Anyway, now I have a glass nail file from the pharmacy for 3 euros and works beautifully.
