I bought the bag (in black) for the university, because I needed a bag where my notebook (max. Screen size 15 ") fit in + power supply + evtl.Maus, folders, pens and meals properly. And this bag is for ideal. The bag offers plenty of room for pens, calculator and any tempo. Just an acute case of Puma, at a reasonable price. And the shipping was once again very fast and reliable, standard for Amazon :).
