If you are looking to add a little texture to your iPhone 4, SlickWraps has exactly what you need. Most people find that cases tend to be very bulky at times and not natural. SlickWraps has a variety of textured and vibrant wraps to keep your phone looking unique without all the bulk.
The latest from SlickWraps is its iPhone 4 Cork Board wrap. This easy-to-apply skin feels and looks exactly like a real cork board. Much like the company's griptape skin, the cork board skin is sure to make your iPhone 4 stand out from the rest.
The Skin Wraps Cork Board design is quite affordable and it can also be made for other devices as well. I wouldn't go sticking any thumbtacks in it, though.
