Green/blue, 3 piece nail file set. Spoil yourself with this top quality, double-sided, 3 piece file set protective sleeves. These files contain no lead. They are also used by many celebrities. Set includes 1-small (3 1/2 inch), 1-medium (5 1/2 inch) for manicures, and 1-large (7 1/2 inch) file for cracked heels and calluses. If you should drop your file on a hard surface, it is designed to break in a blunt fashion. Other types of files that have not been through the tempering and hardening process can splinter and cause injury. The grit on the small and medium file is approximately 200-220 grit and on the large file is approximately 180 grit. Please note, the "grit" is etched into the crystal glass. The cheap imitations have grit bonded onto the surface of the file and wear down quickly. These are the best ones made! You get what you pay for! You'll remember the quality long after you forget the price.
