Artistico Traditional-White Watercolor Blocks are glue-bound on all four sides and are available in cold-press, hot-press and rough grain surfaces. Though Artistico was born as a watercolor paper, it is exceptional for use with any wet medium (acrylic, ink, tempera), in addition to dry mediums (pencil, charcoal, pastels). It also adapts perfectly to all traditional printing techniques. The paper is sized both internally and externally, making it both absorbent and resilient. The paper is mould-made, produced with 100% cotton, chlorine and acid-free, with vegan animal-free surface sizing. Made in Italy using hydro-power. Available in 140 lb. (300gsm).
