Marutenbou Lunch Mat - One-of-a-Kind Denim Size (cm) 28.5 x 42.5 This is a lunch mat from "Marutenbou," known for their Only One Denim products. The embroidery on the denim fabric is lovely. This item is unique and you won't find another like it. I think you can use either side. It has been stored at home unused. Thank you for your understanding. #EriGoods
