I did a lot of research when I was looking for a case for my iPhone 5 - I want something that looks great, is durable, and keeps my phone secure. The Suncase antique leather case is what I went for in the end. It looks biz and oozes classiness - loads of people at work have commented on how nice it is. The exterior is a soft, beautifully treated tactile leather, kind of like saddle leather but with more of a matt finish. It is GENUINE leather, not the cheap, nasty "PU leather" that most so-called "leather" iPhone cases are made from. PU leather is plastic, stamped with a leather pattern...it rips easily and is horrendously rubbish.
Access your phone easily and quickly by pulling the tab, which handily snaps back against the case thanks to a hidden magnet sewn inside. This has proved durable, unlike previous cases of this design which I've owned.No signs of wear and tear yet.
Top notch case, give it a whirl if you're after something classy and elegant.
