From before entering elementary school to elementary school students, it was a very good learning experience to investigate and discuss things they wondered about in their daily lives. It is also recommended for entrance exam preparation and preparation for junior high school entrance exams from lower grades. ⸻ 【Purchase Information】 ・ Recycled materials may be used for packaging, but we will handle it with care. ・ Please note that there may be oversights or omissions due to home storage and amateur inspection.
