Our matboard sheets are full, uncut matboard sheets with 32x40” dimensions. We offer two lines: acid-free and conservation-grade sheets. The stock is an acid-free matboard with a white core for a clean finish. These uncut photo mats are ideal for customization so you can cut your matboard sheets to fit your next project. Upon request, we can bulk cut the full sheet matboards to size for orders over 50 pieces, with a small upcharge. Contact us for this option.
