This is a collection of works by Shoji Ijiri, who was active in the excavation of Lake Nojiri and the scientific movement. It has been stored at home for a long time since it was purchased. The main body is a beautiful book with almost no stains, discoloration, or damage. There are no writings. The outer box has discoloration and damage, so it is listed as "has scratches and stains." The outer box of volume 10 has a slight crack, but the inside of the book is clean. Please check the photos. * We try to ship within 24 hours of purchase, but shipping may be delayed due to circumstances, so we have set the shipping time to "4-7 days."
