I obtained this through a mail-in offer from a magazine. After receiving it, I read it carefully once, and then stored it in a dark place. The cover is made of a material that is prone to scratches, so it had some scuffs and minor scratches from the beginning. They are not very noticeable, but as it has been stored at home by a non-professional, please refrain from purchasing if you are sensitive to imperfections or seek a perfect item.
