What is the difference between white variable files and black ones?

1. The abrasive of white files consists of aluminum oxide, which makes them more plastic, soft and wear-resistant. Black files consist of silicon carbide, which makes them harder, but has a high degree of brittleness.
2. White files have small, rounded abrasive grains that do not injure the nail plate. Black files have sharp abrasive grains that self-sharpen during the filing process.
3. White interchangeable files have a stearate coating that prevents the coating from clogging with organic dust, while black files have no coating.
4. White files work better with dry nail filings, while black files work well with wet nail filings.
5. The white color of the file is more hygienic than black in work, there are no visible stripes or grooves on the file after sawing, and light abrasive particles are not noticeable when they hit the artificial material during nail extensions.
