Dutch firm Freshfiber have just launched these great cases designed for the iPhone 4 and 4s exclusively at Apple stores across the States and Canada.

Designed by Finnish designer Janne Kyttanen, the two designs, 'Weave' and 'Double Mesh', come in a cool graphite grey finish.

Freshfiber is both the first European company and the first company world-wide, to introduce for Apple a line of products made exclusively via 3D printing technologies; made using advanced production techniques which allow complicated shapes and forms that would be impossible to produce using traditional methods.

Aside from looking nice, the clumsy among you might be pleased to hear that the case designs incorporate, from case edge to case edge across the back of the phone, a type of bumper or "crash zone" that assures the case and not the iPhone absorbs shocks when dropped.

In addition, the light and flexible designs encourage increased air flow and cooling capability around the phone, advanced "grip-ability" for gaming, and the high grade laser sintered polyamide means they're easy to clean too.

Perfect.
