Refinery29.com ran a homepage feature about ammo inspired accessories. Here's what they say:
"We're not fighters (more like lovers), but when given the chance to play rough, we're willing to go the distance. Doing a bit of the dirty work for us are these artillery inspired accessories. Comprised of bullet casings and heavy metal, each piece gives a new meaning to the phrase "dressed to kill." Don't blame us if you spend a night in the slammer while flashing one of these baubles. Just make sure to ask the officer for his digits and let him know you're packing."
