Proper protection but just average quality

Ordered this article one month ago, I noticed that the edges were beginning to deteriorate.
Indeed, the coating '' leather '' breaks and reveals the material below.
At the same time, given the price paid, do not expect a 100% quality holster.
However, the protection is effective (back and forward: good screen protection), and the magnet with the small tab always works well.

I just hope that this case will not deteriorate more than that over time.
