What is the difference between white removable files and black ones:

1. The abrasive of the white files is composed of aluminum oxide, which makes them more ductile, softer and more wear resistant. The black files are made of silicon carbide which makes them harder but more brittle.
2. White files have a small abrasive grain of a rounded shape, which allows you not to injure the nail plate. Black files have a sharp-shaped abrasive, which self-sharpenes in the process of sawdust.
3. White replacement files have a stearate coating that prevents organic dust from clogging the coating, black files are not coated.
4. White files work better with dry nail filings, black files work well with wet nail filings.
5. The white color of the file is more hygienic than black in work, no stripes or grooves are visible on the file after sawdust, and light abrasive particles are not noticeable when they get on piece material when building nails.
