This Polierfeile is worth every penny! I have tried quite a few and was often disappointed as they were short-lived. Either the surface used after twice use from or began to crumble. This file is different. Both the matting, as well as the polished side hold out some manicures and meet 100% and its purpose is achieved perfect results. If you want to have high-gloss nails (whether natural, or modeled), is with this file on the safe side!
