Yeah, I think it definitely looks more like charcoal than black. Definitely much lighter than iPhone X black leather case.
I also realize that leather will mark up show patina but 12 case leather just feels so much more fragile than my current iPhone X case. Sure that one mark up too but not nearly as easily, and even those marks usually go away by rubbing them with my finger.
Well now that you mentioned this I also noticed mine got scratch from my fingernail when I felt the wrinkled leather next to camera cutout plastic frame, so a bit too easily in my opinion. I was not pressing hard.
Anyway, sound like my black leather case is not much different from what others described theirs in this thread, so not sure it is worth to exhange it?
One more thing I was wondering about with these Magsafe cases. In leather case there is this ring shaped plastic part touching the back of the phone. Will this eventually cause phone getting marks on the back glass? I think it would be safer if the whole lining was just microgfibre without this ring shaped thing like it has been before.
