Does not sound like enough to the description

Already for me a briefcase has a flap that opens, which is not the case. It is neither more nor less than a bag.
Then in view of the photo I thought it was pretty hard which is not the case. Finally the picture is taken so that the bag is thinner than it seems.
In short, do not correspond at all to what I was looking for.
However, I caution that for the price it's not worth the blow of the back. And I recognize that it seems pretty solid.
