I just purchased these to extend the life of my fruits and vegetables in the refrigerator. They work on the same principle as the green bags. They are foam shelf liners 15 x 14 inches each. They come in packages of 2 or 4 at the present time. I purchased the six package. Looking forward to saving grocery money by extending shelf life of my produce.
