The PalmGuard 13 from Moshi protects the palm-rests on your MacBook Pro 13" Unibody from dust, grease, stains and scratches. The semi-rigid film is form-fitted to the MacBook, providing a nearly flush appearance. A separate trackpad film protector also prevents damage to your trackpad. It's easy to attach the PalmGuard and when you remove it, it doesn't leave any sticky residue behind. Keep your MacBook in perfect condition using the PalmGuard.
