Jo Sonja's Artists' paints are flow formula acrylics offering the opacity of colour and the beautiful, velvet matte finish associated with traditional gouache paints. Unlike gouache, they are water-resistant and will not chip or crack when cured. Made from the finest quality pure pigments, the Jo Sonja's colours will remain vibrant and true for generations. They are non-toxic and waterbased. Choose from 80 exceptional colours including metallics. Suitable for all surfaces including paper, paper-mache, card, canvas, wood, fabric, tin, terracotta, glass and tile.
