***** EDIT! ******
The day after I wrote this review, I got a call from mobile phone Now, where was I informed that it occurred in some cases that these did not have the quality as desired. This is why I was sent to free a new envelope which already eintrudelte another day later with me. Should these cover not qualitatively be zufriedendstellend, I can get the money refunded! Will this second envelope now test and possibly write a new review. But at this point ever: Super Customer Service by phone Now !!
