The POP block series is designed for students and other intermediate advanced art lovers. The ART series is intended for professionals. Both series differ in the basis weight and texture of the paper. Two-sided glued painting blocks with clearly textured paper and high grammage. Intended mainly for wet techniques (watercolors, etchings, gouache, acrylic, tempera and ink). Double bonding and high paper weight prevent paper from creasing under the influence of water. 100% Cellulose, 300 gsm.
