★ This item is from a home collection and does not include an obi. It is a high school textbook guide for Mathematics II Advanced [Su II 317], released on 2018/3/1 by Astro Publishing (publisher) and Bunri (seller), ISBN978-4581184106. Only the book shown in the first photo is included. The cover, top, bottom, and edges have scratches, damage, creases/folds/wrinkles, peeling, label removal marks, and stains. The pages have some creasing and folding, but as far as I can see, there are no markings, and there is no problem with reading. This is a book with damage to the exterior, such as the cover, so please only purchase if you can accept this. If you are concerned or looking for a pristine copy, please refrain from purchasing. The condition has been checked, but please forgive any oversights. Also, there may be damage other than what is described, so please understand this before purchasing. (412183312)
