This is a "Mii-chan's Milk Pack" from the picture book "First Errand" that I purchased a few years ago at a picture book store in Kobe. It's an empty milk carton-shaped box that originally contained sweets. (There are no sweets inside now.) My daughter loves this picture book published by Fukuinkan Shoten, and it's modeled after the milk that Mii-chan, the character in the story, buys on her first errand. The size is approximately 20cm in height and approximately 9cm x 9cm around the sides. The material is thick paper, and it's well-made. It's colored with a colored pencil-like effect. Please note that the listing is only for the empty milk carton-shaped box, and the picture book is not included. I've included the page where this milk carton appears, so please take a look. If you love picture books, are a fan of Akiko Hayashi's illustrations, or are looking for a display piece for your bookshelf or store, or a small container, how about it? Please consider purchasing it.
