Decorating Flake Crystal Flakes are similar to ChroMirror Chrome Pigment Powders, but are made up of larger flakes that provide an intense, super strong shine. 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.
