Ruby Hammer Large Glass Nail File

A Cult Classic, Refined — The Professional Glass Nail File

First introduced to the UK by Ruby in the 1990s, this professional-grade glass nail file is a modern icon — refined, effective, and made to last. The only update to this cult classic is its chic new colour. The craftsmanship remains uncompromising.

Why Glass?

Expertly engineered from chemically-etched tempered glass, this file delivers salon-quality results with each stroke — gently sealing the nail edge to help prevent splitting, peeling, and breakage. At 19.5cm, it offers optimal control and ease whether you’re shaping natural or acrylic nails. Designed to be sustainable and long-lasting, it offers over 10,000 hours of filing time and can be rinsed clean after every use. Sleek, effective, and beautifully minimal — this is nail care at its most refined.
