We offer 3 main types of gumball machines: Gumball Vending Machines, Gumball Banks, and Gumball Dispensers. A Gumball Vending Machine is a commercial-grade machine that accepts quarters only with the standard configuration. However, all of our commercial--grade gumball machines can be converted to a free vend (no coin required) or to accept a token for a gumball machine rewards system. A true gumball bank on the other hand can accept any coin (pennies, nickels, dimes, and quarters). Our most popular gumball banks can be reality converted to free vend and come in three sizes: 9-inch (petite), 11.5-inch (junior), and 15-inch (king) and feature an all metal design with a real glass globe. The 15-inch model also has an optional stand that it can be mounted to for a great decorative item. Our gumball dispensers are generally considered more in the toy category and are simply designed to dispense a gumball with out a coin by pushing a lever or turning the knob.
