Unfortunately, when you own gumball machines, parts sometimes have to be replaced.  If you have the type of machine that has a glass globe that holds the gumballs,  it may have to be replaced if it gets cracked or broken.

Fortunately, you can find those replacement globes on Ebay, and sometimes at a very good price.  That's one of the reasons that I like Ebay.  You can normally find just about anything there. Be sure to  ask the seller questions before bidding or purchasing if you have any doubt about the kind of replacment globe that you need for your particular machine. Sellers are usually more than willing to answer questions and usually get back with you rather quickly.  Replacement globes for gumball machines currently for auction on Ebay:
