Zip Lock Bags
Each zip lock bag is clear, re-closable and contains a single track zipper. All of the bags are made from polyethylene, which contains no PVC and is archival safe. The bags are made of 2 mil plastic that maintains coin safety by keeping dust and moisture out. Zip lock bags are packaged in quantities of 100, and the locking (zipper) portion at the top is not included in the bag size measurement.
