Having bought the holster I find really good value texture is rather mild and do absolutely not damage the phone, however the black color of the case tends to rub off on the iPhone when it is white it which is my case! A force to extend and retract the iPhone, the antenna white inserts blacken what is really ugly in the long run that's dirty! Furthermore it will use a lot of elbow grease to scrub and remove traces as they are tenacious. I tried to put the iPhone in a transparent case, itself set in neoprene pouch and the like, the transparent case went black after one week 1/2 ok so it's cheap but your white iphone will do for much longer with this case !!!
