Motorola has added a third option for people looking to customize the look of their Moto G with new Grip Shells.
The Moto G, which can be ordered directly from Motorola’s web site, comes with a black rear cover that can be swapped with a number of different rear shells. The standard Color Shell costs $15, the new Grip Shell costs $20, and the Flip Shell costs $30.
Each of the shells is available in a half-dozen colors. The Grip Shell, in particular, is a bit more ruggedized than the others and includes a bumper for protection.
