Product Description Made with a pure water-soluble acryl resin, Acryla Gouache is brilliant, lightfast and permanent, and moves, reacts, blends and feels like traditional gouache. However, unlike a traditional gouache which is made with a gum Arabic binder, it does not have a fragile paint film, is compatible with any water-soluble media and waterproof when dry. It also does not shift in color tone from liquid to dry color. Ideal for artists, designers, illustrators, students, hobbyists and bird carvers.
