I purchased this new about 4 years ago. When stored, it was covered with a transparent vinyl protective cover! As you can see in photos 8 and 9, the first volume has some yellowing. I think the other volumes also have some yellowing (I forgot what the original condition was like). There are no noticeable scratches, stains, or folds inside! Please purchase with the understanding that this is the case. <(_ _*)> * The protective sheet will be removed when shipped. No returns.
