"All-Color: A Comprehensive Guide to Sixth Grade English in One Book" by Masao Seki Price: ¥1100 #MasaoSeki #Masao_Seki #Books #Language/English I bought this last year for my child's studies, but they ended up hardly using it, and it's been sitting on the bookshelf. It was kept on the bookshelf, so the cover has a few scratches (please see the second photo), but the inside is very clean with no writing or markings. I would be happy if there's a household that can make good use of it. Please consider it if you're interested."
