Shin Enshu, Grade 5 Math, Volume 1 & 2, with Answer Key and Explanations Volume 1: Pencil markings have been erased. There are two places marked with a highlighter. There are some folded pages. Volume 2: There is writing in red ballpoint pen on only one page, otherwise it is almost unused and clean. Both volumes have stickers covering the names written on the answer key covers. I believe there are no other noticeable scratches or stains, but I apologize if I have overlooked anything. Please consider this item as a used product and understand before purchasing.
