I have looked for this so many times. Why aren’t there packing cubes for notebooks? I’d love to just have a few of them for bringing all my notebooks and gears between home and the office. A few because I’d like to layer it, one with the most important and a few additional for the stuff I sometimes bring.
I can’t be the only crazy ass weirdo who brings a bunch of notebooks, some pens, some other related accessories to the office every single day.
