This is a set of Mobile Suit Moon Gundam volumes 1-13, which is currently serialized in Gundam Ace. I purchased these new and read them a few times before storing them on a bookshelf. There is some yellowing on the top of the books [see photo: 4]. Other than that, there are few scratches, and I think they are in good condition, but since they are used items, there may be some minor scratches or creases. Please understand this before purchasing.
