I bought this intending to study, but I ended up going to school, so I never used it. I bought it at a bookstore and kept it on the bookshelf, so I haven't even opened it. The cover material seems to be one that easily gets scratched, and there were a few scratches on it from when I bought it. The contents are in perfect condition, but please refrain from purchasing if you are overly concerned about minor imperfections. The original price was 2700 yen + tax.
