"Let's Memorize 361 Acupoint Names with Mnemonics - On-Demand Edition" By Hajime Ishii The cover and back cover show stains and wrinkles as seen in photos 1, 3, and 4. I believe the inside pages are free of noticeable stains, but as I am a non-professional, I may have overlooked something. Thank you for your understanding that this is a used item.
