These items will be shipped on Tuesday, the 13th! Selling a 9-book set: 2nd grade (6 books), 3rd grade (3 books) science set. Educational materials from the Shinken Zemi course. These books are packed with children's curiosity, leading to discoveries about "Why?" in the world, history, and the universe, making them say "Oh, I see!" I think it's a great deal to gain this knowledge for around 2000 yen ^^ These are used items that my child has used, so please understand that there may be signs of use and some folds. If you're okay with that, please consider purchasing. Shipping will be from a Yamato Transport directly managed store. Thank you for looking.
