Step 1. Shaping : Using the tapered, yellows #1 file, shape each nail to the desired length and shape. Use the narrow, rounded edge to push back cuticles and remove cuticle residue on the nail. Never cut or remove the cuticle. The cuticle is a barrier to infection. (This file is used a few times each week to maintain the shape of nails as they grow.)
Step 2. Ridges & Smoothing: Using the green #2 file, gently rub the nail surface. (Approximately 20-25 times.) This will remove any stains and prepare the nail for steps #3 & #4. If ridges are present, file smooth these but do not attempt to completely eliminate them. This could result in filing the nail down too deeply. (This file should be used infrequently or lightly to avoid removing too much of the nail surface.)
Step 3. Prep & Condition: Using the white #3 file, gently rub the nail surface. (Approximately 20-25 times.) This conditions the nail and prepares the nail for the buff & shine (step #4). (This file is used once every one to two weeks.)
Step 4. Polish & Shine: Using the gray #4 file, buff to a brilliant shine. (Approximately 20 - 25 times.) You now have beautiful nails without the need for nail polishes. (This file is used frequently and as needed.)
