An archival standard for flat filing, these drop-front storage boxes provide easy access to precious items such as maps, prints, photographs, and newspapers.
The archival-quality black boxes are made from a sturdy, 60 pt, acid-free, scuff-resistant board that is buffered with 3% calcium carbonate to suppress the migrant acidity that results from the environment and from excessive handling. The interior is lined with white paper that has a pH of approximately 8.5.
The boxes also feature adhesive-free, metal-edge construction for additional protection and stacking strength.
The drop-front is on the long dimension.
