I looked at a number of different iPhone cases for my new iPhone 5 and I couldn't find one that protected it without covering up what a great looking smartphone it is.
Then I discovered this brown leather sleeve for the iPhone from a Dutch company called Mujjo. Mujjo looks to make really nice hand crafted pieces out of high quality materials. By the looks of it the workmanship is excellent.
I think this sophisticated protective sleeve is elegant but with a natural feeling from the top-grain hand-dyed leather. This leather sleeve will be a nice compliment for the high-tech looking iPhone.
