This bag is stunning enough in and of itself but it's also super practical. It fits into a tiny case yet it can grow into a roomy shopping and leisure bag. In addition you can close it either with the zipper or with the drawstring. So the end results is a stylish classic shoulder bag or a sporty sling bag in one and then of course you can transform it back into a package the size of a book. How cool is that? When closed- 7.5 by 5.5 by 1.5 inches . When opened up- 15 by 13.75 by 5.5 inches.
