Dun-Dums facts

Interesting fact:

The Dum-Dums suckers with the “?” label are the flavor change over suckers. When they are switching from the first flavor to the next, any sucker produced until the new flavor is fully engaged will go in a “?” label. No 2 “?” will be exactly the same.

This allows for nearly zero scrap!

Engineering genius that most likely came from the line operators.
