Carefully press and rub the flakes into a cleansing-free surface, then apply a coat of Acid-Free Primer and two top coats such as Cool Top Gel. Perfect for encapsulated nail designs. Dip a small bead of Clear Acrylic Powder into Crystal Flakes, then spread it on the nail surface. For gel nails, press the flakes into the soft gel, then cure it.
