Elan Form’s two piece shell snaps snug around your iPhone. It is made of top-grain leather and hard-shell polycarbonate (plastic, I think), to give two layers of protection for your phone. Personally, I like the cork (one on the right)

“Top-grain leather outer shell crafted from hand-matched hides
Protective polycarbonate inner shell surrounds and shields your iPhone
Easy access to multi-touch display, ports and controls
Includes static peel screen protector and premium cleaning cloth
Easy installation: just put your iPhone in the top casing then snapthe back into place. To open the case, insert a coin into the notch in the bottom corner and gently twist. “

Pretty nice.
