I purchased this about a year and a half ago and used it a little. I've progressed in my studies and no longer use it at all, so I'm selling it. I didn't use it that much, but I did carry it around in my bag for a long time, so it shows considerable signs of use. I've erased all the writing, but there are traces of pencil erasures on about 5-6 pages, as shown in the fourth photo. Also, there are stains from ballpoint pen in places (about 3-4 pages as far as I could quickly check), as shown in the fifth photo. The problem sections (problems in each unit, quizzes at the end) were not used at all, so there is no writing of answers, and they are clean. I think it can still be used, so I'll sell it at a low price to someone who doesn't mind. Thank you for looking. Minna no Nigongo Kanji 2 English
