It's so expensive that it's not worthwhile to buy it yourself. If your child learns, you'd better sign up for class. If it is to be promoted in educational institutions, it can still be considered. I've been looking into this Montessori box recently. There are online, Taobao, and early education websites. I don't know if it's one, it's about 60 thousand to 65438+ 10 thousand. If you give it to your own family, the average family can't afford it.
