Help keep photographs and paintings from being bent by adding a piece of backing board behind them. Double Sided Backing Board is 48 point and has a smooth white surface on both sides. BACM8 measures 8" x 10" and works well behind photographs, documents, brochures, signs, and more. Boards are pH neutral. Core color may vary slightly between creme and grey. If shipping artwork, place an extra piece of backing into the mailer for added support and rigidity.
