Open in the front and back, the Hula iPhone 4 case covers the perimeter of your device, protecting all sides, corners, and even the body. The Hula bezel raises the screen and back of your iPhone 4 off the ground when laying flat. The Hula combines two materials: impact resistant silicone to frame your device"s edges and strong, clear TPR plastic between those lines. Together they form a protective band. It"s a layer that absorbs impacts with hard surfaces, with less coming between you and your device.
