Strathmore Museum Mounting Mat Board 1 Ply 32x40

This board is designed for mounting and matting fine archival works of art. The specially treated, acid-free 100% cotton fibers and buffering agent provide enduring protection from the destructive effects of acid. All boards have solid consistent surface and internal color that eliminates off-color bevel mats and affords two usable surfaces. Colors are rated at 80 hours test fade.
