A guidebook providing detailed explanations of the special specifications and models of the S660. While I don't believe there are any noticeable scratches, please understand that there may be signs of use and dirt due to it being a used item. This is just my personal assessment, and as it's been stored by a non-professional, please refrain from purchasing if you are seeking perfection. Please make your judgment based on the photos. I will do my best to ship it as soon as possible after purchase, but I would appreciate it if you could allow a little time. Also, please understand that this is non-cancellable and non-returnable. Thank you for looking.
