If you have thick natural nails or need to smooth the edges of your acrylic or gel nails, this file will be a great choice. The file will also quickly reduce nail length if you prefer to file, rather than cut, your nails.
Gently slide the file along the free edge of 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.
Your file can be gently rinsed to remove file dust and allowed to air dry. Do not soak your file for long periods of time or scrub it aggressively, as this will cause the edges of the grit to lift and curl.
