Most leather totes collapse the moment you take something out of them. They tip over on a desk, they swallow everything at the bottom, and after a month they look like a sack. The ones in this category are built with a structured body and a flat base so they hold their shape empty and sit upright on the floor beside a chair.That construction costs more to make, because the panels have to be cut and supported rather than simply stitched together. It is the single difference between a tote that still looks like a tote in year three and one that does not.A4 flat is the measurement that decides whether a tote is a work bag or a handbag with ambition. Everything here takes documents and a laptop lying flat against the base, so paper comes out the shape it went in.The handles are rolled around a core and stitched closed rather than folded flat, which keeps the weight across the palm instead of on an edge, and stops the handle creasing permanently where it bends.
