Diamond Fret Crowning Files with Fretboard Protector & Finishing Sanding Strips

Diamond Fret Crowning File with 3 Concave files. There are 3 files provided with this tool - 2.0mm, 2.5mm and 3.0mm wide. The ideal file size is a little smaller than the fret width. Also by leaning over the fret side a little, so the abrasion is directed where you want it, the file will cope with smaller and bigger frets than the file width.
