Diamond nail file rust-proof, sterilisable, with fine and coarse grinding surface. Length: 15 cm. Diamond coated nail file. In the production of Remos nail file, the file sheet is made of stainless steel. In addition, both sides of this sheet are covered with diamond grains. One side of it has slightly coarser grains, the other is noticeably finer. Thanks to this material used, the nail file is very durable. The nail file is particularly suitable for manicure. Even with very thick and hard nails, the file does its work exceptionally well. When using the files, the nail edges are automatically sealed and therefore no longer tear as quickly as when working with a conventional nail file.
