This is a paper bag-style lunch bag that can hold two-tiered bento boxes. The outside is made of kraft paper, but the inside is an insulated (cold-retaining) bag that can be closed with a zipper. While not as durable as fabric ones, I believe they can be used repeatedly. The outer bag is old but unopened.
