MUJI's Maternal and Child Health Handbook Case. Size: Approximately 25cm x 15cm. Color: Black. I mainly used it for storage at home, so I rarely took it outside. I think it can be used not only for the Maternal and Child Health Handbook but also for multiple purposes. I kept it at home, so I think it's clean. Please refrain from purchasing if you are concerned about home storage. Returns are not accepted.
