Steps for trimming square nails:

1. Spray diluted alcohol or lotion on your ten fingers, wipe them clean with a towel, and use flat-blade nail scissors to trim evenly from the outside to the inside. Short nails.

2. Make the grinding stick and the bottom of the finger edge parallel, and trim the curvature of the front end of the nail into a horizontal straight line in the same direction from left to right or from right to left to make it square.

3. Place the grinding rod under the nail at a 45-degree angle to the nail surface, and grind in the same direction to make the edges on both sides of the nail arc-shaped.

4. Take double eyelid glue or arc-shaped French nail stickers and stick them about 1mm away from the fingertips, and trim both ends of the nails into symmetrical arc shapes along the stickers.
