The Microsoft sculpt number pad doesn't have an "off" button!!!!
This snap-on cover will protect the keys from being accidentally pressed and depleting the battery. It also gives the pad a nice angle for working and punching in numbers
For storage - place the pad in the cover face down
For work - place the pad face up.
Silicon pads on the bottom are optional - they provide better friction with the table....
This little thing saved me so much grief...
