The first envelope which I had for my Lumia Been schrottreif after 2 days because they should keep the phone at just 5 points with small plastic parts that are broken at the slightest vibration. Here the mobile phone of two continuous "rails" is held in which recesses are let for the side buttons. The material is in spite of the thin (which makes the sheath very narrow and easy to handle and ensures that you can use the side buttons easily) surprisingly stable. The glued leatherette holds perfectly for me (daily use).
