Archive your negatives and prints with this 25-pack of Archive Envelopes from Archival Methods. The cream-colored envelopes are made of a non-buffered 80 lb text paper that is acid- and lignin-free. Each envelope holds up to thirty-six prints measuring 4 x 6". A separate interior pocket holds a roll of 35mm negatives cut into four-frame strips. The front flap of each envelope features a convenient index for important information such as time, place, and subject matter. The same information can be used as a cross-reference for digital files.
