Foam Board 30x40 Large (3/16" thick) BLACK acid-free

This rigid, warp-resistant foam board with its smooth, black 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 dis-colouring over time. CFC-free. This foamboard has the same characteristics as white foamboard, but each sheet is black through and through– black surface and black core.
