For perfect nails, we recommend these professional files. These files are constructed of the finest 3M materials, water-resistant adhesives and premium plastic. When you file, go in one direction. Replace your file often. It shouldn't take more than a few strokes of the file to shape your nail. If you're working too hard, replace the file.
