Gakken's "Why?" series picture books for preschoolers. This is a set of 6 books from the 2022 edition, covering the October to March issues. The stickers have been used. Therefore, the condition is listed as "slightly damaged or with some stains." Otherwise, I believe there are no noticeable scratches or stains. The name has been erased. These are used items, but I hope someone can use them. I will wipe the entire set with a disinfectant sheet before shipping. Thank you for looking.
