Looking to transform your iPhone 4 into a macho-gal? Check out this Sheet metal case made by Ryan Glasgow. The Sheet Metal Case for iPhone 4 is made with 304 stainless steel body, a hinged lid, and elastic band for holding cards or locking the lid in place.
The metal sheet case could protect your iPhone 4 from hard bumps and the inner side of the surface has been properly padded with silicone material to prevent scratches when inserting the iPhone 4 into the case.
