If you recently got the new Nokia Lumia 820 Windows Phone 8 Smartphone, then you might be interested the Active Shell for the Lumia 820. The case was designed and developed specially for the active user who wants to protect their investment.
The Nokia Active Shell was constructed from PC/ABC, a material that was developed to make the shells easy to clip on and off and remain strong at the same time – they allow for easy removal whenever needed, but it adds rubber-like material around the front and the edges. It protects the back of your smartphone and it also stretches around the front slightly to protect the edges of the screen and the corners as well.
The cases are available in the colors of matte yellow, green and orange with a black TPU trim that offers extra protection to the edges in-case of accidental drops and bumps.
