The Mavala Nail Buffer Kit will help to add lustre to your nails. Use the grey buffer to smooth out ridges & irregularities, then follow with the pink pad to improve shine. The circulation at the base of your nail will also be enhanced, which encourages strong & healthy nail growth. Directions for use: Use on dry, bare nails. To smooth out irregularities, draw the grey buffer across the nail in one direction, avoiding the nail tips. Do this once a month. Shine the nail with the pink polisher, using long, energetic, back & forth movements.
