Rock your iPhone.
If you need a sturdy and discreet material to hide your precious iPhone in, why not try a rock? Or at least something that looks and feels like one. UV Production House’s Fake Rock iPhone Case looks like an actual chunk of moss-covered rock, but is actually made from 3 pounds of polyurethane. The case can be used for its primary purpose, which is to protect your iPhone from damage, but can also be used to display or hide your device.
