There is basically no difference at all between Jimmies and Sprinkles. What they are called depends on where you buy them. If you are in the cities of
Philadelphia and Boston, or the states of Michigan and Wisconsin, you will have to ask for
Jimmies. However, in every other part of the world they are sold under the name of Sprinkles.
