The leather is soft and from the inside it feels quite soft, so no scratches should come from the material ... Maintenance: Because there is a small problem: The cell phone sitting pretty tight in the case. The first time I could not get it out of the case, as I had with "heavy equipment" at. Using a pair of scissors I could free the phone from the case difficulty. Unfortunately, this was not without consequences: The gap left its mark in the soft rear of the S4 (unsightly scar).
I wanted the case already send back, but I like the material particularly well, so I gave the case a few more tests. After a few "in-out action" gave the material a bit and now it fits quite well, and it should like to go a little less narrow for my purpose (how long does the mechanism of fabric until it breaks?).
