Carbon fiber is often used in tech and mechanical applications for its resilience and low density; now it's used to make protective mobile cases. Weighing just 11 grams, Truecarbon's carbon fiber phone case is lightweight and slim. Handmade in Italy, it is shock proof and features an anti-scratch coating to keep it looking fresh. And, there's no need to worry about reception blocking due to the strong carbon fiber; the company uses its own formula in the resin to diminish any interception. The phone case is compatible with the iPhone 5 and available for $49.99.
