Lumia 640 XL Case, CoverON® [Slim Guard Series] Slim Dual Layer Armor Hard Cover Thin TPU Phone Case for Microsoft Lumia 640 XL - Teal & Black;

Modern styling: Sharp look and feel
Dual layer build protection: What's better than one layer of phone protection? Two layers.
Slim and lightweight design: Because "I like adding more bulkiness to my phone" - said no one ever.
Screen bevel: Putting a phone face down isn't a good idea, unless you have a lip on your case preventing the screen from actually touching the surface. This case has that.

If you just want to keep your phone protected while actually improving the look of it, the CoverON Slim Guard series case is for you. It's molded to fit the exact specifications of the Microsoft Lumia 640 XL. Crafted in two separate pieces, the inner TPU flexible layer creates shock resistance, while the hard polycarbonate outer layer keeps your phone safe from everyday bumps and dings. The Slim Guard case was designed to be super lightweight and more form-fitting to cut down on any bulky feel, making it easy to handle. Plus, a thin lip protrudes on the front of the phone to protect your screen from directly touching a surface when face down. Top quality looks, protection, and handling all in one case. CoverON offers a 90 day warranty.
