● Sizes Lunch Mat Width: Approximately 53cm Length: Approximately 40cm Lunch Bag Width: Approximately 20cm Length: Approximately 28cm Both the lunch mat and lunch bag have linings. They were made with fabric that has been pre-washed, but there is a possibility that the sizes of the outer and lining fabrics may differ due to shrinkage with repeated washing, so seams have been added to prevent misalignment. I personally don't think the lined lunch mat wrinkles noticeably even without ironing, so I recommend it. If you purchase 2 or more lunch sets, you will receive a 100 yen discount per set. (^^)
