The iPhone 5's glass radio windows at the top and bottom of the back gives it a unique, two-tone look. Most iPhone cases cover this design detail, but the Saturn Case for iPhone 5 embraces it.

Pictured above, the Saturn case is made from polycarbonate and aluminum. The polycarbonate resides over the glass, letting all of the science involved in passing data through the phone continue to take place. The aluminum looks good, and with three color options, you can mirror the color of phone you purchased, or spice things up a bit.
