Ditch your old emery board, this Swiss glass nail file (made of the same superfine material as champagne flutes, of course) is a real game changer. The microfine glass on the filing surface is not only suitable for filing both ways along the nail while still keeping the nail edge smooth and snag free but can also be washed and sterilized to remove buildup and make it like new. Nails? Did.
Take Care: This file can last a year or more (!) if cared for properly. Just wash with soap and water occasionally. If you really go all in for the manicure, put the file in its own cutlery compartment in the dishwasher for a super deep clean that makes it look like new.
