Each pad includes 15 heavy-weight 184 lb. (300gsm) sheets intended for finished paintings, drawings or studies. The paper is acid-free and specially sized for wet media performance with a vellum finish that is excellent for drawing. Ideal for graphite, colored pencils, markers, acrylic, watercolor, gouache, pen & ink, charcoal, gel pens and more. The pads have easy-to-use flip-over covers that keep pages in the pad, yet allow them to tear out cleanly.
