I bought the set of 4 in order to stow away neatly when hiking and trekking snacks can, otherwise just so loose laying around in your backpack. For this the set is obviously well suited, especially since it is machine washable. But even on business trips do the bag Wiebe wrote your service in a slightly larger briefcase. The build quality is good, the zippers are stable, the seams neat. In a nutshell, the product description is true and I am disappointed at any point. No reason to deduct a star somewhere in the evaluation.
