This three-sided polishing file is used for filing, smoothing, and polishing.
Instructions for use: For a professional manicure, file the nails with the black surface in one direction, then polish the top of the nail with the white surface for a beautiful, smooth finish. Finally, create shine by polishing with the gray surface. Please note: excessive filing in steps 1 and 2 can weaken your nails. Step 3 can be repeated as often as desired.
