If you're looking for a unique backing for your iPhone 4, look no further than slickwraps new Cork Board for the iPhone 4. The product is exactly what it sounds like--a backing for your iPhone 4 made of cork board.
As you can see from the picture above, it's real cork board, laser cut and then attached to your iPhone via 3M adhesive backing.
I have to admit that I like it. I'm not sure if the cork would break apart in my pocket, but it's definitely a unique looking piece. It's also priced right at $10--just right for a novelty.
