How to use

Apply a thin coat to bare nails. Once the first layer has dried, apply 1-2 coats of lakur as needed. Let the polish dry for 10-15 seconds. Apply once again over polish to seal in color as a top coat. To expedite the drying process, apply 1-2 drops of Accelerating Drying Oil at the cuticle and allow the oil to run to the free edge of the nail.

For best results, reapply as a top coat every 3-4 days to refresh color and help extend wear time.
