Abstract
A shell assembly includes a shell and an ornamental element attached to the shell. The shell includes a main body with an ornamental area, and a plurality of crossed grooves are defined in the ornamental area. A crossed portion of every two grooves defines a through hole. When the ornamental element is applied to the ornamental area of the main body, air between the ornamental element and the main body can be vented to outside the shell via the grooves and through holes.
