I bought the bag for the first time in December 2013, and now had 7 months in use. Who is afraid that the white of the case is quickly dirty or looks ugly, I can warn. Even after 7 months in use (permanent), there were only minor signs of wear, no scratches, no loose seams etc.
Now on Friday me is my phone fell down a grand staircase from top to bottom and nothing happened. In the case a corner is broken, but my phone did not show any scratches, not walked out, works flawlessly. Since I do not mind paying another 10 Euro for such a good cell phone pocket as the present here :-)
