Photo Storage Envelopes Unbuffered | 4 Sizes | Up To 292 X 368mm

Photo envelopes made from sturdy archival Perma/Dur® Unbuffered stock.

Photo and Negative Envelopes are ideal for long term, safe storage of negatives and photographs. On the recommendation of several photographic archivists, we have changed the seam design and added a new style without a thumb cut. The new side seam construction allows even stacking and filing, and prevents marring of the negative or photo within due to too much weight or pressure.
