Shin-Gakukai's original problem set, a full set of 63 revised editions. All were used by making copies, so there are no writings. However, there are some stains on the answer keys from pens and colored pencils. Please note that none of these affect the text or questions. Photos of the stained areas are attached from the fifth image onwards. We have checked before listing, but please also understand that there may be some tears in the vinyl or slight corner folds due to cardboard storage. There is also a progress schedule (for senior students), but there are circles marked with a ballpoint pen in three places, so please consider it as a bonus. (See the fourth photo; please let us know if you don't need it. There will be no discount.) Immediate purchase is possible. Please purchase if you understand that this is a used item and has been stored at home. Also, please understand that returns, exchanges, and cancellations are not accepted as the materials can be copied.
