50's Randoseru Japanese School BackpackOkay, okay, okay. So This is so cute and stylish The straps are short, so don't expect you (as an adult) to be able to wear it as a backpack, without getting extenders for the straps. But get that done. This bag is sturdy and comes with a "calculator" aka abacus as well as a "lunch box" bentou box. It is made of leather and in great condition. Rounded for extra style and so maybe little pockets. The bag measures 22 cm across, 28 cm high, 12 cm deep.
