Holbein Acryla Gouache is an opaque, acrylic-based watercolor paint, featuring quality, lightfast pigments in an acryl resin binder. It is water-soluble and will dry smooth and matte like traditional gouache, with the added benefit of being permanent, waterproof and flexible once dry - just like artist acrylic. Colors will not shift from wet to dry, making Acryla Gouache the ideal medium for artists, designers, illustrators and students. Acryla Gouache is compatible with other water-based media and available in 102 highly pigmented colors in 20ml and select 40ml tubes.
