Featuring a non-toxic formula and the most permanent, lightfast pigments, Da Vinci Professional Gouache Colors are mixed and milled using the world's finest raw materials. Like other Da Vinci paints, it is made in small batches with trusted craftsmanship and uncompromising quality. For fashion designers, illustrators, graphic artists, and fine artists, Da Vinci Professional Gouache offers an excellent value. While other paint manufacturers produce gouache in small, 15 ml tubes, Da Vinci offers this highest-quality gouache in a 37 ml tube size — offering artists more than double the usual amount of paint for approximately the same price. Titanium White and Black are also available in 150 ml tube sizes.
