Although these shell looks pretty, but here is wrong quality. The envelope was delivered wrapped in foil. When welding it was obvious something wrinkled, so that it is wrong and in leather bottom has a little kink. I hope times, which gives over time. The shell has only exterior genuine leather. Inside there is a velvety fabric, the probably not very long looks so beautiful. Between leather and fabric are sewn cardboard to stabilize probably feels any case like that. Even that should not remain forever in the form. The holder for Smartphone has only 3 stops (1 in the top center, 2 bottom left and right on the corner), thereby shaking the phone in the holder slightly. Here was saved in the wrong place. Still holding the plastic with me, but I still have not made a real endurance test. All in all, the shell acts not very durable, which is exactly the opposite of what one would expect from genuine leather. Therefore I a "Just do not"!
