Color Show's chip-resistant nail polish formula delivers bolder color that just won't quit. Brush on one of the Color Show Polka Dots shades with the easy flow brush for a high fashion 3D nail design. Formaldehyde, DBP, and Toluene free. First apply a clear base coat to prevent your nails from yellowing and to help nail color last longer. With one sweep, paint the first line of polish up the center of your nail, from cuticle to tip. (For the cleanest look, leave a small space at the base of the nail, between where the cuticle ends and polish begins.) Fill in the rest of the nail with one stroke of color on the right and one on the left.
