The PalmGuard by moshi is a wear-resistant film for Apple MacBooks and MacBook Pros palm rests. Made of a high-grade polymer, the cover is bubble-free and splash proof and will protect your Mac from smudges, scratches, and grease. It also comes with a static film track pad and is available online for $20.00 for the Palmguard 13, $23.00 for the 15, and $28.00 for the 17. We wonder if it is also chocolate proof as we have a tendency towards munching on M & Ms during some of our late night activities at the keyboard.
