I bought this intending to use it with my son, but he's approaching junior high school entrance exams, and we haven't gotten around to it. It cost 1760 yen. It's recommended for children aged 7 to 10. You can boost your child's self-esteem by interacting with them in a fun way. A guidebook is included, so please refer to it as you go. It was stored on a bookshelf at home. There may be small scratches, but there are no noticeable flaws. I hope someone will take it off my hands. It's sold out on all websites, so if you're looking for one, please consider it! Here's the description: Supervised by educationalist Katsuki Ishida Let's cast a spell to boost children's self-esteem! An exchange notebook for parents and children.
