From this envelope, I can only advise. When unpacking already met me an extremely chemical smell. I wanted to give the shell still a chance, and even then I was disappointed. the shell does not fit 100% and the magnet for closing the envelope is always in the way. The magnet disturbs especially when one sets up the Händy because there he always hangs over the screen. Because not much will unfortunately be changed because the tape, in which the magnet is installed, is quite stubborn and can not be bent backwards.
