The Toned Blue Mixed Media Pads use heavy-weight mixed media paper that combines the characteristics of a watercolor paper and the finish of a drawing sheet, creating a paper that performs for all wet and dry media. Flip-over covers feature sheets that stay in the pad yet tear out cleanly. These papers are 100% recycled with 30 PCW, are acid-free, and are made in the USA. The pads contain 184 lb. (300 gsm) medium-surface paper appropriate for graphite, colored pencils, markers, acrylic, watercolor, gouache, pen and ink, charcoal, gel pens and more.
