It is a all-in-1 7 sided buffing block for nail art finishing,

ideal for shining and sharping nails perfectly.

Shiny, smooth nails look healthy and make polish last longer.

So buffing your nails is a must.

Some say it even makes your nails less likely to break.

The file has 7 surfaces for seven steps in grooming:

Step 1 - Coarse grit to shape nail
Step 2 - Medium grit to shape nail
Step 3 - Fine grit to neaten edges of nail
Step 4 - Even out
Step 5 - Smooth nail
Step 6 - Buff nail
Step 7 - Shine nail
