All of the gumball machines we sell can dispense 1-inch toy capsules (round and acorn) using the gumball wheel. If you plan on vending 1-inch acorn capsules out of your gumball wheel, please let us know when placing your vending machine order and we will configure this at our warehouse prior to shipment. You can also vend 27mm bouncy balls with a gumball wheel. You cannot vend toy capsules out of a candy wheel, so give us a call if you're not sure which wheel to select upon ordering.
