The Mavala Ridge Filler smooths the nail surface to extend the wear of nail polishes. Filling in the crack in the nails also decreases the risk of nails breaking. Mavala Ridge Filler Smoothes Nail Surface Application: Apply one coat of Mavala Ridge filler on the clean nails. Allow to dry completely and if the nail surface is still uneven, reapply.
