Created in collaboration with artist John Sabraw and engineer Guy Riefler, this limited-edition, eco-friendly set features three, 37 ml tubes of Brown Ochre, Rust Red, and Iron Violet. These exclusive colors are made with reclaimed pigment from polluted waters of acid mine drainage. The pigments are lightfast, natural, and safe. This set also includes a pre-primed, cradled panel made from sustainably harvested North American birch wood and a recyclable sleeve insert. A portion of the proceeds supports efforts to clean the Ohio and Mississippi rivers. Made in the USA.
