Genuine leather and the metal pin is hidden in the bag with leather.
Since I am not a fan of solid cases and covers on the device, the perfect solution.
Having to phone / smartphone while sitting out the jeans fumble just annoys me. Especially in the car, if you sat down again before you've brought the phone out of his pants.
The bag is certainly more mobile phones (it fits so many models) survive and protect effectively. The quality is just right. Priced at just once 20 euros (Feb 2014) even the cheapest leatherette China Cases are projected to the years more expensive.
There is even a 30 year warranty from the manufacturer (registration required).
Have the product for more than a year in daily use. The seams are fine and leather is almost indestructible. Even the imprint still looks very good.
