"Illustrated: Numbers and Formulas So Interesting You Won't Be Able to Sleep" Hirohito Komiyama Price: ¥750 + tax I bought this for my child, but they didn't read it, so I'm selling it as it has been stored on the bookshelf. It's unused, so there are no folds or creases. There are no noticeable scratches on the cover. It has been stored at home.
