The files we produce have soft, and yet highly functional surface, which is gentle on your nails and help to prevent nail splitting.
Roughening is a chemical procedure that is done directly inside the glass and that’s why it prevents abrasive filings from dropping as can often occur in the case of metal, paper, or cheaper variants of glass files where abrasive grains are fixed on the surface.
The surface roughness is determined by the glass type itself and that’s why it is not greatly modifiable. In order to offer files with varied roughness, for their production we use structured surface glass. This method is particularly used to manufacture products suitable for pedicure and men´s manicure.
