This is a set of a mathematics textbook and accompanying exploration notebook for first-year junior high school students published by Suken Shuppan. It is a new, unused, and beautiful item. There are no creases from opening, but the exploration notebook has a crease on the upper right corner as shown in the photo. Both items have names written on them, so the sections with names will be cut out before shipping. Please understand that this item has been stored at home. *I am also selling textbooks for second-year junior high school students. A small discount is available for combined purchases. Please contact me in advance via comment if you wish to purchase both items.
