Foam Board 1/2 inch Thick 20x30 inch White

This rigid, warp-resistant foam board with its smooth, white,  clay-coated surface is ideal for mounting, paints, markers or screen  printing. When cut, the edge bounces back for a clean, sharp edge, and  its resilient core resists dents. Low pH factor helps protect artwork  from discoloring over time. CFC-free.
