The Sow Good Black Cushioned Boards are double sided (100/180 grit) to quickly shape and smooth natural or acrylic nails. Two boards per pack.
Directions Gently slide the file surface over your nail in one direction, not in a back-and-forth, see-saw manner. Repeat until you have the desired shape and smoothness. Use the 100 grit side to quickly reduce your nail length and the 180 grit side to smooth and finish.
Warnings: Keep out of reach of children. See product label for more information.
