This is a set of all four volumes of the TYPE-MOON BOOKS edition and the Material (data book). I purchased them used about 10 years ago. The novels have marks left from removing price stickers. Volume 1 is missing the obi, and Volume 4 has a torn obi. It is said that this edition has more illustrations than the later released Seikaisha Bunko edition. Please research for more details. The Material book includes cover illustrations and status tables that overlap with the novels, but it also contains a glossary and interviews. All books have corner folds, scratches, and stains. In my subjective opinion, the condition is not severe, so I selected "No noticeable scratches or stains." There are no problems with reading them, but if you are looking for a pristine condition, I recommend purchasing from other sellers. Please consider this with the condition understood.
