Pre-cut foam board sheets make fast work of any project! In developing our line of foam board we went to the artist and framer and asked them what they wanted. Above anything else, they wanted a board that was acid-free so they could use it with their original artwork. They wanted a board that allows for mounting without difficulties and the ability to be cut cleanly and bounce back from the compression of the cut. Pro-Foam does this remarkably well. Within the line, there are many variations of thickness and size of foam board. Please note: We cannot guarantee that all corners will arrive without damage.
