Holbein Acryla Gouache moves, reacts, blends and feels like traditional gum arabic gouache and is water resistance once dry. Dries to a velvet matte finish; Holbein Acryla Gouache does not shift in color tone from liquid to dry color. This unique paint does not have the same fragile surface as traditional gouache in gum arabic and is compatible with all other water soluble media regardless of origin
