Purchased about a year ago and stored in a dark place after reading once. There is almost no yellowing. *Please note that there are scratches on the cover and stains on the back cover, so it is not recommended for those seeking a perfect new item. I own a cat. There is a possibility that cat hair may get mixed in during packaging, so please refrain from purchasing if you are concerned. Instant purchase is welcome, and it will be sent via anonymous delivery.
