"Hajimete no Kikukiku Drill: Nyumon-hen" (First Time Listening Drill: Introductory Edition) I have opened it, but it is unused. I opened the CD case to check the CD's functionality. It works fine. Although it is unused, there are brown stains on the cover and the first two pages. I think I may have accidentally put some colored pencil lead shavings inside. Please check photos 2 and 3. Thank you. Hideki Wada / Hiroaki Murakami Price: -1400 yen #HidekiWada #Hideki_Wada #HiroakiMurakami #Hiroaki_Murakami #book #Language/Japanese"
