These Polypropylene Photo Sleeves are sealed on 3 sides, short side is open. They are archival, made of cast polypropylene. They are clear and easy to read through. They are made of a heavier polypropylene than our envelopes, and feature a completely sealed closure (as different from our fold-locking closure sleeves). While the fold-locking style is nice for fragile items and photos, these closed style protectors are secure and safe to use for most items.
Just slip your item into the protector from the shorter end.
