They have been stored on a bookshelf at home, so please consider that they have the usual signs of wear and tear for their age (stains, yellowing, scratches, etc.). They are in reasonably good condition (please check the images). I have checked them and found no major unsightly damage, folds, or writing, but there may be oversights. Please purchase if you understand this. Shipping will be via "Yu-Packet Post". There is a possibility of changing to "Rakuraku Mercari Bin", so please be aware of this before purchasing.
