It does it's job as a phone wallet encasement, but not super great. My case was clearly made of cheap material so it started scratching a few weeks into using the phone. It does get easily scratched. It's been a few months (around 3), and at the corners, most of the gray has rubbed off. I really like the bezel which keeps my phone safe, and I haven't gotten a single scratch, though.

Ex Output:
3

This product work great. I have been giving these to my dog for a few months now and he barley sheds. He loves getting them every morning as a treat. They work wonderful and it is such a great price for them.
