Original, foam-core graphic arts board is made with polystyrene extruded foam laminated between two sheets of paper to form a lightweight but strong and rigid surface. Ideal for crafts, school projects, framing, mounting, displays and exhibits. Foam board has a smooth, satin surface that can accept a wide range of media, including paints. Sheets are easy to cut, warp-resistant and dent-resistant. Foam board is 3/16" thick and easily dispenses from Pacon Poster Board Racks.
