Thank you for viewing. This is a set of high school math textbooks from Suken Shuppan. They are currently compatible with the "New Curriculum" used in high schools. [Product Contents] 1. Mathematics I (Suken Shuppan) 2. Mathematics A (Suken Shuppan) [Condition of the Product] Writing: There is no writing in either book. I have checked them briefly, and they are in good condition. Mathematics A: This is a new, unused item that has never been used since purchase. There are only slight scratches on the cover from storage, and the contents are like new. Mathematics I: This was used in class, so there are some minor folds on the corners, but there is no writing inside, and you can use it without any problems. Name written: None [Recommended for:] Those who want to keep another copy at school for "leaving at school" Those looking for clean textbooks for preparation and review Those who want to get new curriculum textbooks at a low price [Shipping and Packaging] To prevent water damage, the books will be placed in a plastic bag and then shipped in an envelope.
