"NHK 3-Month Master MOOK: Mathematics - That "Aha!" Moment of Understanding, Again" "NHK 3-Month Master: Drawing" "NHK 3-Month Master: Einstein" Purchased new and then cut. All three books have been cut. Other than being cut, they are in very good condition. You can read them page by page. I will sell them to someone who understands this. Thank you. #Akiki Yokoyama #Akiki_Yokoyama #Book #Nature/Mathematics
