As already written, so far everything well, no flaws, looks very nice, is well stabilized, so that nothing pushes on the back or deform. However, in order to open the knapsack, two slides have to be pushed in at the same time the right and left on the side of the closure and that's not quite so easy to do for little hands. Our daughter manages indeed now, but it took just a little practice, at the beginning it was not at all and I already thought to return the satchel. But our daughter wanted to keep him absolutely, and now it will work to some extent.
