Last month I've discovered a new design company in Japan that was getting ready to release an aluminum bumper for the iPhone 4 called the Deff Cleave, and it was like no other bumper case. Well now the Deff Cleave bears a new name for the American consumers and that is the Draco IV aluminum bumper case. Inspired by Deff Japan, the Draco IV is breathtaking. Never have I seen such uniqueness in a aluminum case for the iPhone 4. The Draco IV's curvatures are out of this world and may remind you of an exotic sports car you always wanted. Check out the full review right after the break as we dig deeper into this fascinating aluminum bumper.
