Thank you for viewing my listing among many others. Helpman! Volumes 25, 26, and 27. This is a set of 3 books. As these are used books, some volumes have age-related yellowing, but this does not affect readability. The condition assessment is a総合評価 (overall evaluation) of all volumes (the condition of individual books may vary slightly). Please check the condition of the books in the photos. *Please note that the color may differ slightly from the actual product due to lighting.* The pricing is based on Amazon's market price at the time of listing. I plan to gradually lower the price if the item does not sell for a while. As the price includes shipping and fees, please refrain from price negotiations. *Prices may increase due to market fluctuations.* I want to sell everything in this listing, so I am not considering selling them individually. After a simple cleaning of the book covers with alcohol, they will be packed in OPP film and shipped. Please understand that these are used items that have been in someone's possession. Those who are concerned about minor scuffs, creases, or dirt should refrain from purchasing. Due to shipping circumstances, the shipping method may be changed from "Rakuraku Mercari便" to "Yuyu Mercari便" (or vice versa). No comments are necessary; immediate purchase is OK. Even if negotiations are in progress, the first person to purchase will be prioritized. I may use recycled cardboard for shipping. Thank you for your understanding.
