IPhone 5 screen protectors for the side?

I have recently just bought a brand new iphone 5 and I don't want any scratches on it is there any way to prevent this I need something for the sides where the volume is I already have a back and front screen protector thanks

It's called a case… -.-

The sides don't get scratched anyway, but everyone that has an iPhone knows that it's pretty much impossible to have one without it getting scratched at some point.
