Thank you for viewing. Asvel Stainless Steel Insulated Lunch Box 800ml This is a set of a lunch box and a case. Capacity: Rice container 0.4L Side dish container 0.4L Heat retention (rice container only): 53 degrees Celsius or higher (6 hours) I bought this for my child's lunch, but they only used this lunch box a few times. It's in good condition with little signs of use (^^) The bottom of the containers is also clean (photo ⑥) There is white staining on the lunch box case (photo ⑦) I will ship via Rakuraku Mercari.
