ZAGG InvisibleShield Case Friendly Smudge-Proof Screen Protector for Apple iPhone 4 / iPhone 4S

The invisibleSHIELD Smudge-Proof is protective film that improves screen visibility by filtering and polarizing harsh light, making gadgets easier to use in daylight and well-lit office environments. Made from the same durable material as the original invisibleSHIELD, this film also helps diminish the appearance of smudges and fingerprints while providing unbeatable scratch protection. Our exclusive, patented film with nano-memory technology covers and shields your device, keeping it as pristine as the day you took it out of the box. The precision pre-cut invisibleSHIELD is designed specifically for your device. The invisibleSHIELD applies directly to your device, providing the toughest, most durable protection you will find. The invisibleSHIELD has its origins in the military, where it was used to protect high-speed helicopter blades from dust, dirt and debris. Now you can use that same powerful technology to protect your device. The invisibleSHIELD is only .2 millimeters thick; making it the slimmest case or cover of its kind. It is so tough that we back it with a lifetime guarantee. So, if it ever does wear or scratch, we will replace it for free, for the life of your device. And if you ever need to remove the invisibleSHIELD, no problem; it comes off clean and leaves no sticky residue.
