I have a very light, very thin carbon fiber case on my iPhone.
No, I did have a case but it was a pain XP I did draw all over my phone tho!
No, not really.
Nope. I have a hot pink trident case on it, which is pretty much a knockoff brand of an otterbox in a way. I don't like the color pink, but it was the only color they had left at the time and I really needed one😕
