A straight black nail file with a very versatile 100/180 grit surface ideally suited for both artificial and natural nails. The high-quality abrasive paper is washable and extremely durable. Excellent comfort of use thanks to the robust centre, the good foam and the quality abrasive paper. The nail files follow the standard Grit designation. The smaller the Grit value is, the rougher the file. The 2-part designation refers to both sides of the file (for example, a 100/100 file has 100 grit on both sides, a 100/180 file has a 100 grit and a 180 grit side).
