I purchased all 37 volumes new as a set, so they have clear covers. Volumes 38-45 were collected individually, so they do not have covers. I will not sell them individually. The condition is good, and I believe they are in beautiful condition, but this is based on my personal opinion. Please check the photos. You can purchase immediately after reading my profile. Regarding used books, please understand that there may be oversights such as yellowing or minor scratches that do not affect reading. I do not list items in extremely poor condition, but please refrain from purchasing if you are looking for perfect condition. I will package them in waterproof packaging for shipping.
