Bring your imagination to life with the Strathmore® illustration board. Each of the illustration boards in this pack of 10 is mounted on both sides of a lignin-free, premium grade white board. This creates balanced tension and prevents warping. You can use a variety of media on this art board, including colored pencils, oil pastels, graphite pencils, markers, and sketching sticks. The 20 inch x 30 inch boards are ideal for collages and light washes.
