This is a set of six "Child Books" from the 2023 edition, covering the months of October to March. I purchased them for 400 yen per book. They were purchased at a nursery school, so they have the child's name written on them. Also, the sticker play sections have been used, but I've left them as they are, so you can still play with them. Other than the sticker sections, I think they are in beautiful condition with hardly any signs of use. These books have been used by a small child, so please understand this before purchasing. I am also selling a set of six books for the first half of the year, April to September.
