【Cut and Prepared】Dialogue-Based Mathematics Classroom, Complete 6-Volume Set (Iwanami Shoten) Koji Shiga This product is "cut and prepared." (The pages are separated one by one) Therefore, the condition of the product is listed as "Has scratches and stains." Please be aware of this. As far as I could see, there are no markings, but please forgive any oversight. At least, there are no noticeable markings on most pages. As these are old books, there may be sun damage, stains, and dirt due to aging.
