There are several different types and sizes of bags, and these sizes usually depend on the purpose of the bag. Fashion bags are usually small in size, while "functional" bags (like shopping bags) are significantly larger. However, regardless of the intended function, people always prefer their bags to be highly portable. Unfortunately, the larger the bag, the more challenging it becomes to move them around.
This bag, however, has a perfectly portable design so you can take it with you wherever you go. It also has a foldable construction, so once you have folded it, you can easily keep it in your purse or backpack.
