Hello! I am offering a set of "Kagaku-gumi" (Science Group) books. The issues are not consecutive, but they are like an encyclopedia, so if anyone is interested in reading them, please consider purchasing them. You can learn a lot just by having a few of them. There were originally cards as supplements, but they are not included. There is no problem without the cards, but please refrain from purchasing if you are concerned. ☆ I am also offering other "Kagaku-gumi" books. If you would like a different combination, please comment. ☆ If you only want one book, I will sell it for 450 yen. Thank you. A set of learning magazines for 2nd graders with a science and engineering theme. - Title: Kagaku-gumi 2nd Grade: The Secret of Money - Title: Kagaku-gumi 2nd Grade: Earth and Space - Title: Kagaku-gumi 2nd Grade: Working Thank you for looking.
