This is a KEY SET, not a keyboard, for the Acer Chromebook C720. This key set contains every key normally found on the U.S. keyboard. If you've got broken, damaged or otherwise unusable keys, you can use this key set to replace any individual keys you may need.
TL;DR, We offer key sets that are functional, but still attached to palm rests.
As many key sets are not normally sold, we elected to offer them as a reclaimed product. This means any of the key sets we offer are perfectly functional, though still attached to the normal keyboard that we would normally fail due to our high quality standards. So you may receive your key set still attached to the palm rest, but we can assure you it's quite simple to remove the keys you need.
