I received this item from someone else. Please check the year of publication in the photos. There was a small pencil mark on the first page of the practice questions, which I erased with an eraser. I believe there are no other markings, but I apologize if I missed anything. The answer booklet has been detached from the main book. The red sheet is not included. Please note that the shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin.
