This is the 6th edition (list price: 900 yen, excluding tax). I've flipped through it about three times and as far as I can tell, there are no writings or stains, but I may have missed something. There is some scuffing and discoloration on the cover. Please understand that this item has been used by a child. I am also selling a set of two books from the same series: Classical Japanese and Classical Chinese. Please feel free to ask any questions you may have.
