It was important that the casing also goes all around the corners and the long edges of the S4 rum, because there I had previously ever quirks of my phones. It is quite narrow on the corners and edges and does not contribute to particularly. The function screen timeout when closing also works, and when you open it, the display is back. When closing the display briefly comes with the time and it's black and saves power :-) The term "leather bag" I find a bit confusing because it definitely only plastic (PU) is, even if the door is covered with beautiful inside something soft, so that the display can happen. It also includes good without tab, button or Velcro. Am completely satisfied, they've ordered in white and of course it is now so slow a bit dirty, they will therefore ordered me in a different color.
