A high school student used to read these, but I'm selling them to declutter. I bought all of them new at a bookstore and stored them in a dark place when not reading them. The books themselves are in beautiful condition with no yellowing. Only volume 1 has a crease on the color cover (photo 6). I am a non-smoker and I do not have any pets. Please understand that these are used items stored at home before purchasing. I will wrap them in cushioning material, reinforce them with cardboard, and take waterproof measures before putting them in a paper bag for delivery. I may use recycled materials for packaging. Thank you for your understanding.
