Gouache paints are ideal for art classes and learning mixing techniques. Over 80% of the ingredients are of natural origin. They adhere to various materials such as paper, cardboard, wood, and salt dough. Once dry, they are matte, opaque, and non-cracking. The paints offer excellent lightfastness and intense, creamy colors with high opacity. The bottle contains 30% less plastic (PET). The Caran d'Ache Gouache Eco watercolor is excellent for art education. The colors have a high pigment concentration and very good opacity. Even when heavily diluted, the color intensity remains intact. You can use Gouache Eco on various materials such as paper, cardboard, wood, glass, and metal. The paint is also suitable for children aged 5 and up and can be easily removed from hands, benches, and tables with soapy water.
