1 Pack A4 File Box Paper Organizers Holder, Transparent Document Paper Project Case, Plastic Paper Storage Container Box File Protector for Magazine, Scrapbook, Office School Supplies

It’s annoying that the majority of travel bags have dedicated laptop compartments if you don’t travel with one. It’s a bit more space and weight but it can add structure and padding. I use the Patagonia Black Hole 32 and the entire back panel is a laptop compartment. I use the space for my folded rain jacket. Of course it can be used for documents, magazines, maps and other flat thin objects. You can buy plastic document/project storage boxes that are about the size of laptop. One Redditor filled one the small toiletries and first aid items. I could see one bring used for small tech cables or camera accessories. They can be surprisingly heavy: the one linked below is 250g/8.8oz. https://www.amazon.com/dp/B0D2HMKRLR
