Zebra File 50ct - 100/180 Grit

What is this file good for? 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. 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.  File Specs: Cre8tion Zebra File 80/100 Grit (Coarse) 7.5in x 1in
