Thank you for viewing! This is a set of high school math textbooks from Suken Shuppan. They are compatible with the "New Curriculum" currently used in high schools. [Product Contents] 1. Mathematics II (Suken Shuppan) 2. Mathematics B (Suken Shuppan) [Condition of the Product] Writing: None in either book. I have checked them briefly, and they are in beautiful condition. These are unused items that have never been used after purchase. The contents are like new. Name written: None [Recommended for:] Those who want to keep another set at school for "on-site study" 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, I will put them in a plastic bag and then ship them in an envelope. I am also open to price negotiations, so feel free to comment. I will ship them the same day during the end of the year period!!
