I've looked through it, and there are no markings. Please check the condition of the book in the photos. *Please note that the color of the actual item may differ slightly from the photos due to lighting. Please understand that this is a used item that has been handled by someone else. If you are concerned about minor scratches, folds, or stains, please refrain from purchasing. Due to shipping circumstances, we may change the shipping method from "Rakuraku Mercari Bin" to "Yuyu Mercari Bin" (or vice versa). No comments are needed, and immediate purchase is welcome. We will prioritize the person who purchases first, even if negotiations are in progress. We may use recycled cardboard for shipping. Thank you for your understanding. *Please note that there may be oversights as this is a personal inspection.
