Most of metal iPhone 4 cases are made of aluminum, but apparently Case-Mate’s metal case is more premium. It’s a titanium iPhone 4 case.
As we can see from the images, this is an ultra-slim iPhone 4 case, or we can say it’s a metal iPhone 4 bumper. Unlike other metal iPhone 4 case, this one by Case-Mate is machined from a single piece of titanium, which is often used in aircraft engines and luxury automobiles. This means its ultra strong construction can effectively protect the iPhone 4 from impact and scratches, while the accompanying button protectors can also keep dust out of your iPhone. Apart from that, the all iPhone 4 buttons and functions can be accessed via those button protectors, and the blank back allows you to show off your cool vinyl decal.
Case-Mate titanium iPhone 4 case is priced at $300 USD. If you’re interested, jump to Case-Mate official site for full details, or check out the demo video first.
