Our Crystal Nails Zebra and Xtreme files both have long lifespan. Due to the newest particle adhesion technology the Xtreme files are the longest lasting files ever. The flexible gritting does not scratch or slide on the surface but clings onto the material and removes it better.
The Xtreme files are made of Superior Grade Japanese Paper. Our Zebra Professional files have a softer grit than the Xtreme and are ideal for surface refining and use on the natural nail.
