Quirky PLUM1-BK01 Luminum Case for iPhone 5 - Retail Packaging - Black Echoing the form of the iPhone 5, Luminum is a minimalist case that dwells on the beauty of brushed aluminum. An anodized aluminum inset replicates the iPhone 5s iconic finish in a variety of colors, giving you more freedom to express yourself while staying true to the devices original form.
