The XK-A-1139-R is a 10 pack of a single keys blank legend sheet. Stickless legends align themselves inside X-keys key lenses before you snap them on the key cap base. When you peel off the legends the adhesive remains on the backing sheet. All sheets are 8 1/2" wide and 5 1/2" high and come ten to a pack. Legends peel off and nest under X-keys keycaps. These are best suited for hand written legends on all models of X-keys. Not suited for printing on a computer.
