Whether you're at home or in the salon, this professional nail buffer makes it easy to create a long-lasting shine without damaging the natural nails. Side 1 (320 grit) is designed to shape and smooth away ridges on the surface of the nails. This helps to create the perfect canvas for your manicure, ensuring maximum adhesion and longevity. Side 2 (600 grit) polishes the nails to refine the surface for a silky-smooth finish. Side 3 (3000 grit) gently buffs the nails to a natural, healthy shine.How to use:Side 1: Holding the buffer parallel to your nail, use unidirectional strokes to gently buff an X shape. Cover the entire nail to ensure even results. To avoid thinning the nails, only use 6-8 strokes. Once completed, this step should only be repeated once there is new nail growth.Side 2: Gently buff the nails as above, using 4-6 strokes. Repeat this step every 2-3 weeks to stimulate growth and maintain healthy, smooth nails.Side 3: Using a light pressure, gently buff using tiny circular motions over the entire surface of the nail until it reaches a natural shine. This step can be repeated every few days to maintain a glossy finish.
