Set of two. Characters from Aranzi Aronzo. The mesh part folds up compactly. You can put sandwiches or rice balls on top, and side dishes on the bottom. Approximately 13 x 10 cm, height 10 cm, 5 cm when folded. I used them a few times when I was little, such as for school trips. They have been stored away since then. The rubber band has some stains, but the inside is clean. Thank you for looking.
