Dum Dums lollipops are an American candy institution – they’ve been around since 1924. There were 7 flavors to start with, now 16 plus the Mystery Flavor. Did you know that the Dum-Dums “Mystery Flavor” is the result of the end of one batch mixing with the next batch, rather than making a brand new batch! If you grew up licking a Dum-Dums Know Your Flavors then you are part of the Candy Societee and this t-shirt is sweet on you.
