This is a Miffy household budget notebook. It's not the calendar-linked type, so you can start using it anytime. I bought it before the pandemic because my grandchild liked Miffy, but I never used it. I took it out of the bag for storage, so I'm selling it at a low price. It originally cost nearly 2000 yen.
