I’ve seen “tire tread” cases for phones before, but never have I seen one with a touch of glamour. The Diamond Case for iPhone 5 from Musubo is a “hybrid design” case. It has a hard, glossy, translucent panel that’s been formed with a diamond pattern. The edges are made of protective, impact-resistant TPU. The case allows full access to the iPhone 5′s buttons and ports, and it comes with a folding stand. The Musubo Diamond is available in purple or black in the US from Amazon for $29.99 (see the product link, above).
Note: I haven’t tried the Diamond Case, but I have used the Musubo Retro case on my iPhone 4 and my iPhone 5. I love them for their cool retro style and their protectiveness. See the related posts for a link to my review of the iPhone 4 Retro.
