Gumball Machine

There are a few different considerations for buying gum for your gumball machine:

Size

First of all, there are different sizes of gum. Gumballs typically come in 1/2 or 1 inch sizes, so be sure to get the gum size that is right for your machine. If you have a small personal gum machine, usually this will be the 1/2 inch size. Commercial machines that sell gum for a quarter each use the 1 inch size.

Flavor 

There are multiple flavors of gum available for machines.  Usually, the smaller variety pack of gumballs will come in one flavor, but you can find them in different flavor or even find a refill pack all of your favorite flavor. One inch gum is usually available in  greater flavor variety.

Color

When selecting gum for a gumball machine, color can be an issue. You can have either multiple colors or all one color. You may wish to choose one color if you are selecting gum for a wedding favor machine or if you are trying to draw attention to a commercial machine by a black machine with all white gumballs, for example.
