San Jose, California-based mod-3 has introduced the RADIUS for Apple‘s iPhone 5. Billed as “the only aluminum case that showcases the iPhone 5’s design elements with its ultra minimalistic approach” and weighing in at less than 1/5 of an ounce, the RADIUS is a bold departure from conventional bumper and snap cases and consists of a simple aircraft-grade aluminum x-frame along with four corner bumpers and stainless steel screws to connect the pieces. » RADIUS Case: Minimalist Case for iPhone 5
