I purchased this book new and only read it once, so the inside is clean. However, the cover came off and got crushed under the bed, so the cover has multiple wrinkles and folds. There are no problems with reading the book. Please purchase only if you don't mind the condition. It will be shipped via Yu-Packet Post. Thank you.
