Why is Wolfcub different?

Wolfcub is made with love in the Czech Republic from the finest Bohemia Crystal.

Ultra-fine filing surface

Unlike many other glass files, our unique filing surface is etched directly into the glass - our proprietary process achieves the very smoothest and most consistent surface. Effortlessly turning nails to dust, Wolfcub is highly effective but completely non-abrasive on skin so will never cause pain or irritation.

Double-hardened glass

After the surface is etched, we use a special tempering process to harden the glass. This makes Wolfcub much tougher than other glass nail files - in fact, our files are over three times as strong as some!

Safe for baby

Each Wolfcub file is finished and polished by hand, to ensure that there are no sharp edges. Our files have been independently tested for safety, and meet all applicable EU health and safety requirements.

Wolfcub can be washed and disinfected for perfect hygiene and is so durable that it will never wear out - in fact, we guarantee it for life!
