This is an anodized aluminum lunch box from Teinen Kogyo. It also has a chopstick holder on the side. It will be provided with a divider and a small, sealed container (made by Teinen) inside. It has a wonderful atmosphere and is lovely. There are scratches and dents, but I don't think there's much dirt. Please check the condition in the photos.
