This 50-pack of 8.5 x 11" Acid-Free Card Stock from Archival Methods is designed to have many uses. The card stock can act as a support, and prevent photographs or documents from bending inside of archival pages or sleeves. Photographs or documents can be mounted onto the stock and used as an album page. The stock can be used as a backing for a photograph inside of a frame. Instead of marking a matted print, you can write on the card stock, for information or easy identification of a print.
