All Warpaints Air are pre-mixed and ready to airbrush right out of the bottle. They are made from highly filtered vibrant pigments. The Warpaints Air range has been developed in a unique and innovative Triad system. Each corresponding Warpaints Acrylics color has a matching base and highlight color. This makes highlighting and zenithal shading easier, while painting your army becomes even faster and more consistent. Warpaints Air comes pre-loaded with two stainless steel mixing balls for easy use.
