Remember the wooden backs for Moto x, I talked about. Now a bamboo wooden back for Motorola Moto X is available On Moto Maker for extra $100. 

The wooden back is not available yet but it's appearing on Moto maker. According to Motorola, these backs wont ship until January. The backs are only available online.

"Moto X with Bamboo will be available online only*, for $199 with a new two-year contract with Verizon, AT&T and Sprint, or unlocked with no contract for as little as $0 down with special financing terms."

Wooden back adds a nice touch to moto X and you should definitely give it a go if you like to try new things.
