Due to weight and packaging considerations, all 20 volumes will be sold in three separate shipments. This item is exclusively for those who purchase all volumes, so we appreciate your understanding. Published between 1972 and 1974, all volumes are first editions, first printings. Includes the supplement "Kotoba no Mado" (Window of Words). Stored in the storage room of my parents' house, in a bookshelf with glass doors. It's likely that they were hardly opened after purchase, and were mainly displayed on the shelf. The text is in remarkably good condition, considering it's been over 50 years since publication. The cases show some signs of aging, and some volumes have slight staining on the top, bottom, and side edges. As it's not possible to check every page, please understand that this is a casual inspection before purchasing.
