Graft Concept amazed us with its unique luxury timepiece-inspired Leverage case for the iPhone when we had the opportunity of reviewing it first hand. And now, the company has taken its Gadgetmac award-winning case design and as expected, created the Leverage i5 case for the iPhone 5. The $50 Leverage i5 is a sophisticated mixture of improvement over the original. The Leverage i5 is a slim polycarbonate case which lets you rock it as a fully protective case with the included removable backplate or in a bumper-style fashion. It features a unique and now iconic metal lever latch mechanism for quick release and installation which was inspired by high-end watch clasps.

In addition to the built-in metal sleep/wake button located in the lever, one of the new improvements that come with the Leverage i5 case is an integrated metal volume rocker button. Graft Concept has also created an optional $15 card holder backplate accessory for the Leverage i5 that can replace the included flat plate with one that has a card slot which can store up to three credit cards.

And if you're one of the first 2,000 people to pre-order the Leverage i5 now, you get one gratis. iPhone 5 users will have the option of choosing between a black rubberized matte finished Leverage i5 or a glossy white case with the option of either a matte or chrome polished lever. The Leverage i5 case for the iPhone 5 is expected to start shipping in the month of January of 2013.
