This is a mini picture book of Yuka Shimada's "Bam and Kero's Cold Morning," which is popular not only with children but also with adults. Originally, it was my son's favorite picture book, and he would often bring the larger version when he went to stay overnight, so I bought the mini picture book for convenience when going out. The size is about 13cm x about 17cm, and although it's mini-sized, the illustrations are exactly the same as the larger picture book. It's a size that easily fits in a bag or a child's backpack. Also, please note that a book cover (transparent book protection cover) has been applied to the cover to prevent friction in the bag. The inside is in beautiful condition with no tears, folds, or writing. Yuka Shimada's "Bam and Kero series" is very popular not only for the main characters, Bam and Kero, but also for the supporting characters such as Yamepi, who looks like a dog, and Ojigi-chan, who looks like a rabbit. The stories of Bam and Kero and the small stories of Yamepi and Ojigi-chan are happening simultaneously on the same page, so it's fun to find out what has changed from the previous page. Why not enjoy them with your child when you're out and about? Please consider purchasing it.
