【Vocabulary Book】 It seems to be usable without any problems! There are some stains and folds. Please see the photos on the 1st, 2nd, and 3rd pages. There are a few check marks on the first few pages, but about three-quarters of it is completely unused. Accessories like the red sheet are also included. There is no cover! 【Workbook】 This also seems to be usable without any problems! However, there is writing on the first set of questions, as shown in the 11th photo. Also, the answer sheets that came with it are not for six years. Please be aware of this ( * . .)" The separate answer booklet has no writing in it! I am accepting price negotiations! I may not be able to lower the price to your desired amount, but please feel free to comment (*^^*)
