The bag is made of synthetic leather with ordinary processing. It is slightly larger than the iPhone 6, which means that this can be a little slide around in your pocket. But that's not a problem for safety, as the magnetic closure but is quite strong and not give in even in strong shaking of the bag. In addition, the removal is facilitated. The side with the magnetic closure ("back" of the envelope) is strengthened somewhat, providing better protection for the display.
My only drawback is that the leather is relatively soft and can thus bend the lower corners. This allows plugging in your pocket, especially in narrow pants are a bit handicapped.
Who can ignore the fact that I can still recommend the pocket.
