Czech tempered glass
Ground from borosilicate glass — the same material used in professional nail salons. Stays sharp for years and never sheds abrasive particles onto the nail surface.
Works wet or dry
File at the sink, in the bath, or anywhere. Water doesn't degrade glass the way it destroys cardboard emery boards — the surface stays consistent every time.
Seals the nail edge
The fine grit closes the nail tip as it files, reducing splitting and peeling — the opposite of what rough emery boards do. Smoother edge, longer nail.
How to use
Two steps to
better edges.
File in one direction
Work from the outer edge toward the centre in smooth, even strokes. Avoid sawing back and forth — one-direction filing keeps the nail tip sealed and prevents the micro-tears that cause splitting.
Rinse and store
Rinse under warm water after use to clear away nail dust. Pat dry and return to the sleeve. A glass file kept clean and stored correctly lasts indefinitely.
