Precautions while using Nail Paint
Take off any old polish
Soak a cotton ball or round in some nail polish remover and hold it against the nail for ten seconds. Then swipe the cotton ball along the nail to remove the polish. Use a q tip soaked in nail polish remover to get rid of any polish trapped around the edges. Itll serve as a protective coat and help keep your nails strong as you practice polishing regularly.
