This is a learning magazine for second graders, covering various themes in science and social studies. It consists of 12 volumes and is packed with content that stimulates children's curiosity. Purchased in the 2023 academic year. *Each month, there was a bonus "Knowledge Encyclopedia Card" at the end of the volume, but some months' cards have been removed. Overall, the books are in good condition, but there may be some folds. Also, as shown in the second photo, issue number 9 has stickers on it. As shown in the third photo, the name on issue number 5 has been blacked out. There should be no problem with reading them. This was an optional add-on from Shinken Zemi, costing about 1000 yen per book. I apologize if I have overlooked anything. I hope those who understand that this is a used item and that the inspection was done by an amateur will consider purchasing it.
