We offer this new easy and fast fret polishing tools. These don’t have the problem of steel wool. Erase the small scratches or polish the dirty frets. Because of their softness, the rubber fits to the fret arch perfectly and won’t deform the fret. Also the soft rubber keeps the fingerboard damage to a minimum (still need tape protection if the eraser will rub the fingerboard). They are easy to cut with a knife for easy shaping or hard to reach areas. Come in three different grits 180/400 grit set (1 of each size) or a 1000 grit set(2 pieces).
