Genuine Czech "Bohemian" Glass Nail File - Bona Fide Beauty Czech glass nail filers are the real deal. All of our glass fingernail files are handcrafted from the Czech Republic with tempered Czech glass. The fine grit is etched into the nail file body and not sprayed on.

Comfortable Nail Filing in Any Direction - unlike other traditional nail files, Czech glass files can be used in any direction. Expertly trim and shape natural nails with comfort and efficiency. Start with a light pressure when first filing your nails, and increase pressure as you go. With every filing, the nails edges become sealed and smooth.

Durable, Long-Lasting, Reusable Czech Glass Files - Bona Fide Beauty nail files are tempered (strengthened) glass ensuring durability. This double-sided nail file has its fine grit etched on which contributes to the nail fool being long-lasting.

It's Still Glass! Though made of tempered glass, the glass nail file can break if dropped or tapped against hard surfaces. With proper care, a Czech glass file can last a long time, making it a reusable and sustainable choice.
