Get creative with your iPhone case. The Krizzle is the iPhone 5 case that you design yourself. Each Krizzle set comes with a transparent case to protect your phone and 40 sheets of a specially perforated sketch pad. You (or your creative friends) draw whatever you want on the pad, then rip off the sheet and slip it into the case. Now you have a unique completely custom work of art on your phone. And you can change it whenever you want.
