I got a gumball machine and it is awesome. I don't like candy. I purchased clear plastic containers that can be filled. Just like you see in any regular vending machine. I would not say they have a perfect seal on them. I am not sure what to fill them with. I was thinking trail mix or some sort of nuts. I would imagine that it won't get emptied in a long time. I am not sure how long it will be. So I need something that will last for a long time.
