This 50-pack of 32 x 40" 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.

The white card stock is made out of alpha-cellulose pulp from purified wood fiber. No dyes, non-bleeding, and no alum were used in the manufacturing process. A lignin- and acid-free stock, it is pH-balanced at 9. Alkaline sizing was used internally and externally on the card stock, which has passed the Photographic Activity Test (PAT), confirming it is suitable for long-term storage. The weight of the card stock is 290 gsm.
