I never used this book after purchasing it. There's a crease on the left side of the cover. The answer key has been removed. The upper left corner of the answer booklet is slightly torn. I think it should be fine to use (see photo 3). - Title: Regular Test ZUBARI Yokoderu English 3rd Year - Publisher: Shinko Shuppansha Keirinkan - Price: 792 yen - Answer Key: Included Please understand that this item has been stored at home.
