Simply clear archival polypropylene photo sleeves!
These archival protectors are made of polypropylene. They are clear and easy to read through. They are made of a heavier polypropylene than our envelopes, and feature a fold-locking closure.
Polypropylene Photo Sleeves are sealed on 2 parallel sides. They are open on the shorter ends. They feature a fold lock tab that allows you to open and close easily, getting your fragile photo in and out much more gently than a closed design does.
