InvisibleShield

If you want to go that extra step in protecting your MacBook, check out the InvisibleShield ($55). The scratch-resistant clear film protects the top, bottom, touchpad, and wrist rests of your MacBook. The InvisibleShield material is super tough (note the picture of the futile attempt at puncturing with a pen). It was originally created by the U.S. military to protect the edges of helicopter blades. The InvisibleShield comes with a lifetime warranty, so if your MacBook ever does get scratched, the company says they'll replace it for free.
