These are my own design...featuring 100% cotton mesh and 100% cotton toppers. These toppers add a lot of stability to the mesh portion of the bag along with pretty designs. These bags are meant for large items that are bought at the market by item and not by weight as the bags themselves do add weight. So when you are at the market and they want to dump those potaotes from the basket into a plastic bag, give them your pretty cotton mesh bag. Great for ears of corn, brocolli, celery, lettuce....tons of stuff!!!
