Genuine GERMANIKURE, hand crafted in Czech Republic and inspected for quality by fairly paid adult artisans. | Recommended by Professionals – The super fine, even surface is the healthiest choice. Without the danger of sharp, inconsistently glued abrasive crystals, our files do not cause microscopic frays and gouges. This file is prefect for smoothing heals, removing calluses, and filing toenails. | Filing Surface Guaranteed - Some glass files are made by gluing harsh abrasives to the surface. Not only is that bad for nails, they WILL wear out and need to be replaced! The surface of our files is permanently etched and guaranteed for life. | Hey - Its Glass! Friendly reminder, it’s made of glass! We made our files 5mm thick and chemically tempered to protect against breakage. Treat it like you would a favorite wine glass & this file can last a lifetime. | Nail Care For Grown Ups - GERMANIKURE refuses to participate in child labor and worldwide pollution.
