This is a supplement from Shinken Zemi Elementary School Course. You can enjoy learning kanji through manga. All of these were issued within the last 3 years. There are some page folds and minor writing, but nothing that makes the text unreadable. The first-grade one had stickers, and some of them have been used. All three books have been used by a child, so please refrain from purchasing if you are concerned about the condition. Please understand that these are used items before purchasing.
