We've only been waiting for Xiaomi to release new wooden back covers for its Mi4 flagship phone and they're finally here. You can choose from among the six three wooden-bamboo designed covers. There's bamboo Bangkok, white oak, walnut, black apricot wood, and rosewood. These smartphone covers cost only 69 yuan ($11) each so it's really a great buy. You'll get a nicer looking and well-protected Xiaomi Mi4 at an affordable price.
