The case is nice to look at, but it has serious disadvantages: First, the push button slides through the opening at the closed end of the case. That means you pull out the key and the Filzbeutelchen can come loose and fall to the ground. On the other hand, I realized that Felt is not optimally suited as a material for a key case. It causes too much friction plain, with the result that it is difficult to get the case quickly out of his pocket or to let it fall back. Leather is as smooth and easy everything goes a little easier on the hand. Therefore, unfortunately, only two stars.
