CAZE (http://www.iphonecaze.com/) has announced a new new addition to its family of Zero 5 series for the iPhone 4S/4: the US$19.90 Zero 5 EX, which the company claims is the world’s thinnest clear case for the Apple smartphone.

It measures 0.5 millimeters. The camera hole of Zero 5 EX has been made larger according to the Apple Case Design Guidelines to prevent flash diffusion. Also, CAZE has put a black ring surrounding the hole in order to avoid glare when taking pictures with flash.

The Zero 5 EX (0.5mm) is a bit raised to protect your screen from further scratches when laid on a flat surface. The package comes with a free screen protection kit (front and back films).
