Our Electronic Tip Jar is a real crowd pleaser. It senses a hand near the cup and rings a bell that sounds just like a real Boxing Ring Bell. 16 bright red L.E.D.s light up to the sound of the "ding" from the bell. Built in On/Off Switch and Volume Control. No Assembly required. Entire assembly is 18 inches tall and 7 inches wide.
