This handy file block is a must have in your collection. With this polishing block you ensure that you make your own nail slightly rougher, so that the gel adheres better to your own nail.
How does it work?
Step 1: Sand your own nail lightly with this file, and repeat this on all nails.
Step 2: Apply the gel polish in several layers and harden the gel under a UV or LED lamp.
