The low-cost smartphone features a slower (than the iPhone 5S) A6 processor, LTE cellular networking, and an 8-megapixel rear camera.
It also comes with iOS 7, which will be released on September 18 for free.
Apple claims the budget smartphone, which costs from $99 on a two-year contract, is "for the colorful."
Though the back case is made with plastic, Apple claims it has structural integrity, making it "pleasingly solid to the touch."
The background wallpaper matches the color of the case.
You can see the rounded corners of the iPhone 5C, reminiscent of the older iPhone 3GS.
Cases can be snapped on and taken off at will.

Apple says iOS 7 was "designed with the colors of iPhone 5C in mind."
The low-end (but still high-spec) smartphone goes on sale later in September.
