These backing boards along with comic bags are the most common way to protect and preserve your comic books.
They are full 24 point one side coated board, solid bleached sulfate, buffered with 3% calcium carbonate and precision cut to size. They are completely acid free and independent lab tested.
Slip your comic into the bag with a backer board behind it (shiny side toward the comic), fold the flap over and secure with a couple strips of tape.
Size 6¾" x 10½". 100 boards per pack. Price is per pack.
Note: Due to these being a bulky item, the weight is a dimensional weight rather than the actual weight. Recent changes by the US postal service in charges to ship bulky items results in higher costs to ship these items using priority mail.
