This listing is for one lighted business card billboard. Light on top illuminates the business card. The card light is powered by a 9v battery that inserts into the back by simply taking a flat head screwdriver and prying out from one of the two slots on the side of the cover in the back. 9v battery in not included!  Business cards slide in from the side. Billboard is approximately 6 1/2 inches tall. Maybe a tiny bit taller.  Platform it sits on is approximately 1 1/4 inches. Space to put business cards in at the bottom will hold a stack of cards approximately 1 1/4 inches thick. This was 3d printed and put together with hot glue.   Very awesome piece, if you don’t like it contact me, I accept returns for any reason!
