This is a set of 12 books, one for each month from the April 2024 issue to the March 2025 issue. These were used by a 4-year-old throughout the year. The books were used at the child's kindergarten, so the stickers have been used and will be sent as is. Also, there is a name written on the back, which will be marked out with a marker before shipping. They are relatively clean, but since they were used by a child, please understand that there may be some folds or creases before purchasing. #Nakayoshi Mate #Picture Books #Children's Books #Bundle #Set Sale #Year-round #4-year-olds
