4-Flap Enclosures

4 flap envelopes offer comprehensive mechanical and climatic protection for glass plate negatives and photographs. The four flaps protect your image material from scratching and prevent possible glass breakage. Ideally, glass plate negatives should be stored standing on their edge, not tilted, in an archive box.
