This is our Grifiti Fat Palm Pads! These are 1/4 inch thick instead of 1/8 like our Slim Palm Pads. These are meant for users that need a bit more cushion and don't close their Macbook or laptop too often. You need to remove these to do so, which is easy to do! They are only non-skid and not sticky. We optimized for comfort and portability. You see, we tried a bunch of the super thin leather and clothe MacBook wrist rests that all cost a darn ton but we came away feeling like we just had no support for the money. The nice thing about them was that they allow you to close the computer while leaving the cover in place. We also tried the super fat gel laptop wrist rests out there from a couple of good vendors. They offer a ton of cushion, which some people like, but these where just a little too tall for us and a bit too bulky to pack away easily on the road so we work on a happy medium... Fat Palm Pads have a satin smooth silicone surface for resting your hands. Great new addition to the Grifiti Palm Pad, Slim Wrist Pad 5,12,17 and Fat Wrist Pad 8,12,14,and 17 lineup! Try these with a Deck 13, 15, or 17 lap desk as well!
