Where can get a one direction iPhone 5 case?

A cheap one

EBay or amazon

A dumpster, where they belong.

Okay.

Claires or justice would have things like that

Probably amazon

Https://www.skinit.com make a custom one

Better idea, don't get a one direction phone case.

Why do you want a one direction case? Get a Justin Bieber one instead.
