In addition to the previously announced bamboo finish for the Moto X, Motorola Mobility officially unveiled the rest of the well-leaked wood backs for its Android flagship on Friday.

The new backs, which Motorola calls “Wood Finishes” are available in Ebony, Teak and Walnut and will add $25 to the $399 off-contract price of the Moto X. Motorola says that the Moto X finishes are made out of real wood, and will each feature slightly different grains.

The Moto X can be customized and ordered with the new backs on the company's Moto Maker web site already. Motorola announced a release date when the wood-backed Moto X would begin shipping -- Tuesday, Jan. 21.
