We offer a wide selection of comic and magazine backing boards that are made from a variety of materials including cellulose fiber, Solid Bleached Sulfate (SBS) wood pulp, and "clear" Polyethylene Terephthalate (PET). These backing boards vary in thickness and rigidity from the regular 24-pt. white boards to some much thicker 60-pt. and 80-pt. clear boards. Some boards are buffered and coated on one side, others are non-coated and buffered throughout, and a select few are entirely 100% acid-free and will remain that way for a lifetime of archival protection.
