Input: This is a nice book. I was a bit disappointed however, since it says 'used' but the first page looks so great that you know that it's not... It has deep water stains on several of the pages and feels like the book itself may have been opened before. Other than that, my son loves it, he likes how bright the colors are. It's very colorful in fact - the pictures are really bright. Just be careful not to open or rip it.
Output:
Good Review
