June 30, 1988, 3rd edition ● Volume 2, "Butterfly's Grave," has a small dent on the cover, but otherwise, there is no significant damage, although there is some yellowing of the pages, spotting on the edges and around the covers, and some stains on the inside of the covers (volumes 5, 6, and 7 are a bit noticeable). The covers still have a shine, and the books appear to have been read very little. ● Cleaning has been done using alcohol, etc. ● We will take measures to prevent water damage when shipping. ● Price negotiations are not accepted. The price will be gradually reduced. ● Immediate purchase is OK.
