The new iPhone 4/4s case is the same design as the iPhone 5 case we released in September 2012. The case is made from a close-grained bamboo exterior and a solid surface material inner basin, which strengthens the case and is revolutionary in its smooth feel.
You can choose either a white or black front bezel to match your phone. A wooden actuated button tops off the case and has a satisfying click to it each time you lock and unlock the phone.
I hope this helps answer your question!
