The Leather Back case from Brando Shopping cost $10 which is a fraction of the official Apple Leather case.

Unlike the Apple Leather case it’s a one piece plastic with leather effect. IMO it looks great in the red finish and will look not discolour like the Apple case does.

It is available in the following colours –

Black
White
Red
Pink
Lime
Cyan
Coffee

Model:
iPhone 5
iPhone 5s

Package Content:
One piece Plastic Back Case

Both my wife and I liked this case and it only adds 10mm to the depth of the iPhone.
