How to choose the right nail file?

The higher the grit number, the smoother the file. 

• Coarse files (80-100 grit) are best for acrylic nail extensions. 
• Medium files (120-180 grit) are best to shape extensions of medium thickness, like most tips and wraps, and to shape the free edge of toenails. 
• Fine files (240-600 grit) are best for removing small bumps, ridges or discolorations and for shaping the free edge of natural nails. 
• Ultra fine files (600-2400 grit) are used for buffing and shining all types of nails.
