Glass nail files–also called crystal nail files–are precisely what they sound like. Instead of using a harsh emery file, glass files use much gentler grit that doesn’t cause damage to our nails but instead smooths our rough edges without a downside
How to Use
Filing your nails while they’re dry, and in one direction only (not using a back-and-forth motion), will give you the smoothest edges. The glass grit is very gentle and great for natural nails. To keep your file working its best, rinse off any file dust after use.
