Unfortunately, "droning" the shell, however, already made. While the flap at the beginning very closely sat and went close with a bit of pressure, it is now so easy that it constantly opens by itself and folds down. This is very annoying and should in an envelope at this price do not happen really.
If you change the phone accessories like many a time, then that is certainly sufficient. I had, however, for the price a product expected that I can use constantly over a longer period.
