XFiles Designed in USA High Quality Japan Sandpaper - Regular White Color (50pcs)

Please note: Individual files may not include printed grit numbers.

Nail files are graded according to the grit per square inch. The numbers refer to how course the grit is on the nail file surface. If both numbers are the same then both sides have the same grit- if the two numbers are different then both sides have different grit.

For example, a 180/180 grit file means both sides are the same and that there is 180 grit on 1square cm, or 80/100 grit file means one side is 80 and another side is 100 grit

• The higher the number, the softer the file grit;
• The lower the number, the coarser the file grit

80 grit: Extra coarse

Used for heavy product removal or for shortening artificial nails faster. 

100 grit: Coarse

Used to take the length down and to shape side walls and free edge

180 grit: Fine

Use to contour the whole nail; to prep natural nail before applying any product, also during manicure to shorten or shape natural free edge, and give a beautiful shape and nice, smooth finishing to artificial nails
