All volumes were purchased new by me. They have been stored in a case in a dark place. Volumes 9 and later are all first editions. Individual sales are not possible; please purchase as a set. The earlier volumes have some yellowing due to age. However, I think they are generally in quite good condition. Please refrain from purchasing if you are overly concerned about the condition, as these are used books. I am not able to offer a discount on this item.
