Bainbridge 1/8" Acid-Free Foam Core is the finest available. Unlike other foam core boards sold elsewhere, ours are 100% cotton and acid-free, never yellowing, becoming britte or harming your work. Foamboard makes a perfect addition to our archival mats, protecting your valuable work for generations to come.

The 1/8" thickness is ideal for backing your prints, greeting cards and photographs, as it will fit into any of our crystal clear sleeves. Give your work more presence and depth by using a foamcore backing in your presentation sleeve. It will stand out more in the display racks and bins.
