AMP Colors are developed in partnership with the Atomic Mass Games studio and based on the world-renowned PRO Acryl formula! They deliver the same premium high-density pigment in a superior acrylic medium, giving great opacity right out of the bottle and allowing all colors to thin evenly to achieve any level of transparency. They are formulated to provide the same consistency in color and coverage, whether applied with a standard brush or airbrush. All paints come with an innovative, no-clog cap that provides the benefits of a dropper bottle and twist cap all in one. They also come loaded with PRO Acryls signature glass agitators and are sealed for freshness!
