Skinny case

I have an Iphone 4 and my main problem is to find a case that interacts very little with me. I want to feel the phone in my hands not to have it all covered. I think this design covers everything. It`s cool, modern, maintains the phones beauty and it gives the phone protection in the sensitive areas and still is cheap to manufacture. It can be done in different colors and different logos can be attached to it (sorry for not integrating the GrabCAD logo, i just didn`t had time). Hope you like my entry!
