The Wood Ebony S Series is a naturally sleek snap case specially made to fit the iPhone 5/5s. At 0.9mm thin it is a single layer, multi-pressed wood veneered outer shell infused with DuPont™ Kevlar® fibers. These fibers make it 5 times stronger than steel at the same weight and will not block your GPS, Wifi or cellular signal. Each case is polished to a durable finish to protect against scratching.
