Each sheet includes twenty 1/3 inch (7.5 mm) diameter dots and six 1/2 by 1/2 inch squares. When you order a Smart-NAV system, one sheet is included in the box. When you order this accessory separately, two sheets are included.
Extra dots are useful for attaching to other items like glasses, hats, microphone booms or even your forehead. They should last 6-12 months depending on use. Heavy users may want to stock up!
