This is the size of the lunch mat, designed to fit the desk tops of most Japanese elementary schools (unless otherwise specified). Size (approx. cm) ⚫︎ Mat: 40cm (length) x 60cm (width) ⚫︎ Bag: 25cm (length) x 20cm (width) x 5cm (depth) *The lunch mat's length is approximately 39cm, so the price has been reduced from 1,390 to 1,350. ♡ This is handmade, so it's not perfect, but I think it's easy to use and care for. Thank you for your understanding. ~That's all~ Thank you very much for looking.
