These bags are strong and very clear polypropylene for superior readability and easy viewing. They are archival and uncoated. They serve as protective storage for almost anything. We fold the bags for shipping - if you only order a few, they will be folded. We fold them gently to minimize creasing, but they will crease some. Below the zipper, the bags measure 12" x 14-3/4". These bags were made in Taiwan.
