The polishing block with 4 surfaces is particularly suitable for removing fine to medium imperfections on the nail edges. In addition, the natural nail can be perfectly matte and slightly roughened. On slightly roughened natural nails, modelling and nail polish lasts much longer. If no nail polish or modelling is desired, one side of the buffer can give the natural nail a beautiful shine after the manicure. In nail art, the polishing block can be used for careful filing and re-grinding. To finish a modelling with gel or acrylic, the high-gloss polishing block can be used to conjure up a diamond-clear shine. The buffer has the right side for every work, because its four sides have different fine surfaces. The buffer is particularly gentle on the nails thanks to its fine grain.
