The complete 11-volume Saikyo-Oh Zukan series, with special editions for UMA and Air. - Series Name: Saikyo-Oh Zukan - Publisher: Gakken - Volumes: 9 volumes total - Special Editions: UMA Saikyo-Oh Zukan, Air Saikyo-Oh Zukan + Dangerous Creatures VS Dinosaurs & Ancient Creatures Death Race Super Battle Picture Book Thank you for viewing. The covers are clean as my child removed them while reading. Some covers and back covers have creases, but there is no writing, and some books haven't been read much, so they are relatively clean. - The Dinosaur Saikyo-Oh Zukan is missing its cover. Also, it was the most read, so there are creases on the corners of the cover. - There are also creases on the cover and back cover of the Character Picture Book (black cover and back cover in the image). These are used books that my child has read. For those who don't mind (^^)
