How to use OPI Edge White 240 File:

1. Start with clean, dry nails.
2. Gently file the edges of your nails with the coarse side of the file to shape them.
3. Switch to the finer side of the file and lightly buff the surface of your nails to smooth out any ridges or bumps.
4. Be careful not to file too aggressively or apply too much pressure, as this can damage your nails.
5. Use the file in one direction, rather than back and forth, to prevent splitting or peeling of your nails.
6. After filing, wash your hands to remove any nail dust or debris.
7. Apply your favorite nail polish or treatment to complete your manicure.
