Directions for use

1. Blue one for filing nail edges, not for nail surface.

2. In pink, one should file the relief on the surface of the nail in one direction, but do not file excessively. If the nail is thin, you must be careful.

Green one is often used to smooth the surface of the nail.

Yellow one can be used at any time to rub the surface of the nail to give it a sheen.

Tips:

Use green and yellow filing surfaces at least once a week to maintain a smooth finish.

2. Pink. Green and yellow rasps are double-sided and can be used on the underside.
