Fabriano BLACK BLACK and WHITE WHITE pads contain acid-free paper made of ECF cellulose pulp. Ideal for pastel, color pencils, markers, paper craft, portfolio presentations and mat boards. Although not recommended for pure water techniques such as gouache and watercolor, the heavier weight takes light water media. The pads are glued on top, and include 20 sheets of 300gsm, a versatile weight to maximize uses. Available in two sizes: 9" x 12" and 8" x 8".
