They're made of wood.
2 piece case, but there's a little "lip" inside that keeps it from pulling apart. There's a very specific way to pull it apart.. it would be IMPOSSIBLE to get it to do this without intending to take your phone out of the case.
They're a little pricey ($55), but they look pretty slick, aren't too bulky, and come with a stand and screen protector (if you're into that).
I've had mine for a few weeks, quite enjoying it, and had quite a few compliments on it already.
you can check 'em out here if you're interested www.itimber.com
I also HATE the baggy effect that starts happening to many cases after a few months of use. I had a graphite griffen case for a few months. Loved it for awhile... far from bulky, the "bumper" area offered grip... then after a few months, the outer edge near the "home" buttum sagged, and became level with the surface of the front of the phone. Garbage.
For what it is worth it is www.itimbercase.com[url] not simply...ide any protection to the face of the iphone?
