Jiyū Jizai (Free as You Like) - Elementary School Upper Grades This is a set of 4 books: Math, Science, Japanese Language, and Social Studies. Purchased in 2022. I used them as a reference when helping with塾 (juku - cram school) homework, so there are no markings. I looked at the Science book the most, so the帯 (obi - paper band) is creased (see photo 2). I hardly used the Japanese Language book. I believe they are in good condition, but they are used items, so please refrain from purchasing if you are concerned. Thank you.
