Thank you for viewing. This book has been stored on a bookshelf for a long time. I think it's relatively clean, but as you can see in the photos, the corners of the pages in the latter half of the book are slightly folded. There is also some deterioration due to aging. I don't think it will bother you when you read it, but please understand that this is a used book before considering purchasing it. Author: Satoshi Yamaguchi
