Our NATIONAL GEOGRAPHICMAGAZINE BACKINGSare properly sized to fit into OUR polybags. Placing a backing behind your magazine, then putting it inside a polybag helps prevent the magazine spine from crushing and the magazine corners and edges from crimping or wrinkling. We carry three grades of magazine backing boards - backings for short-term, long-term and indefinite storage. To see the material specs for our backing boards click here.
NOTE: Backing boards will not fit in National Geographic Sleeves SNG3 & SPPNGRR. These sleeves hold the magazine only. If you choose the extra support of using a backing board, please see the related products associated with each style backing below.
