This gouache is easy to apply and work with and dries in a few minutes. It adheres to any grease-free and porous ground such as paper and board, but also to wood, plaster and earthenware. Once dry, the work has an attractive velvety mat finish. Each set contains 20ml tubes of three primary colors (cyan, lemon yellow and magenta) plus black and white. The 8-color set adds yellow, vermillion and ultramarine dark.
