This is a set of volumes 19 and 20 of "Tsuiraku JK to Haijin Kyoushi" (Falling JK and the Pervert Teacher). * Volume 20 is a first edition. I purchased these at a bookstore and have only read them once before storing them. There are no noticeable stains or scratches, and I believe they are in excellent condition with little wear. There are absolutely no problems with reading them. I will package them with waterproof protection for shipping. *Please refrain from purchasing if you are overly concerned about the condition, as these are used items.
