This is a random set of the regular edition, paperback edition, and long edition. I've collected only the volumes I like. *Two volumes of Kiteretsu Daihyakka have been added. This is a set of 30 books in total. Thank you very much. - I used a Carl DC-200NA cutter and cut the books as carefully as possible. The covers have not been cut. - Please understand that this item is for scanner use. - I've only scanned them once, so I don't think there will be any errors in the order of the pages, but please forgive me if there are any.
