The "Crystal" series of screen protectors is a single 99% transparent, washable, multi-layer composite piece designed to fit the entire screen area of the iPod Classic. It may be used with any of our skins and comes with the screen protector, a microfiber cleaning cloth and application squeegee. As you'd expect from a DecalGirl product, there's no nasty goo or residue once it's removed from your iPod!
