Holbein Acryla Gouache is an opaque, acrylic-based watercolour 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. Colours 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 colours in 20ml and select 40ml tubes.
