This might be the most serious phone case I've ever seen. Made of stainless steel and looking like some sort of strange torture device, it's certainly a different look than Apple's Bumpers.
It features a lid that flips all the way around, a rubber band to keep things quiet or securely closed, if you want, as well as some really nice-looking detailing all around. Of course, it doesn't look all that pocket-friendly, but then I don't think too many cases are.
If you're looking for a case that will both protect your phone and intimidate your friends, this looks like your guy.
