Nokia did not spend much time talking about their Lumia 820 smartphone at the recent event where they announced Lumia 920.

The company has now posted a blog post about the interchangeable shells that would be available for the Lumia 820 model.

Interchangeable shells on Lumia 820 would allow users to change the color of their phone at any time. Regular shells are available along with a special edition which would add support for wireless charging on the device.

The company said:

Made from PC/ABS – 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. And the colors aren’t just painted on; they are inherent in the material. This means that if you were to scratch the shell you won’t be left with a noticeable mark, you’ll actually hardly notice it’s there. It keeps its color for longer. When you buy a Nokia Lumia 820 you’ll receive a standard shell in the box, made from the PC/ABS material. High gloss colors available are red, yellow, cyan, purple, and white. Matte colors are grey and black.
