The June 2022 issue of Takarajimasha's "steady." magazine comes with a "Miffy Foldable Big Bag" as a bonus. This large-capacity bag can hold a lot and has a cooling/heating function, making it perfect for shopping in the coming season. It also folds up compactly and can be secured with a snap button for easy carrying. The top has a zipper to conceal the contents. Although unused, it has been stored at home.
