The first is a chrome case by more. It fits the 3G or 3GS. It has light scratches, but still in good shape. Asking $7 shipped.
The second is a real carbon fiber case. I paid $60 for it. It has very minor scuffs as well, but not that noticeable. Its real carbon fiber, so you can buff the scratches out. The case is super thin and is hard to even notice on the phone. This was my favorite case when I had my 3GS. I would like $27 for the carbon fiber case shipped.
