Crafted in a European mill that has been making fine art papers since 1618, these watercolor paper blocks are made with paper-making machines that are able to operate at very slow speeds, creating a sheet that shares the strength and quality characteristics of more expensive mold made papers. Each block contains 15 sheets of 140 lb acid free watercolor paper bound on two edges, offering the benefit of both a pad and a block and allowing for easy movement from one sheet to the next.
