In my five years as an iPhone owner I have never once used a case (well, except for the Morphie Juice Pack Air) — I prefer my iPhone sans-case. But, many an iPhone owner prefer or need a case. And if you (or your friend) want something that is sleek, snug fitting, and minimal then I highly recommend the Barely There case from Case-Mate.

My brother-in-law has this case and I like it more than any other iPhone case I've seen. It is very snug, it has a high-quality matte plastic feel, and it doesn't have one of those annoying circle cutouts in the back that show off the Apple logo.

The Case-Mate Barely There is half price on Amazon and ships free for Prime members.
