From $20

Forget about boring phone cases that always keep the same look. Pegit allows you to change your case along with your daily wardrobe – or your look. Made for the iPhone 5 or 5S, it's a pegboard case with modular panels that swap out, allowing you to create your own colour palette. There are six individual panels that can be customised, so there's a bit of scope for creativity here. And, of course, it will protect that delicate smartphone from the bumps and knocks it is bound to get on a daily basis.
