Excellent PRO One Coat Ultrabase with acid – an acid base for use in shellac and gel manicures on problematic nails prone to air bubbles and lifting. It is ideal for difficult nails, including hard nails that require more etching. It perfectly increases the adhesion of products applied later. Multifunction Grafen Base can be applied over ULTRABASE WITH ACID.
CAUTION! We do not recommend using it on weak, thin, damaged or filed nails.
