Kodomo Challenge Hopp For 3- and 4-year-olds, educational picture books April 2023 - March 2024 A set of 12 books for one year ◎ Stickers are mostly used. Through the picture books, you can learn about daily life activities, friendships, various rules, etc., and it also serves as a guide for parents to understand what is expected of 3- and 4-year-olds. In addition to being educational materials, the books also contain various stories, so you can of course enjoy them as picture books. I think they are in relatively good condition, but since they have been used by children, please understand that they are used items. Instant purchase is OK. Thank you.
