Sen-Sen is a type of breath freshener originally marketed as a "breath perfume" in the late 19th century by T. B. Dunn Co. It looks like tiny squares of black licorice. Sen-Sen was to the 19th century what breath mints are to our time.The ingredients of Sen-Sen are imported from Bulgaria, France, Turkey, Greece, Italy and some almost inaccessible regions of Asia. The product is still made on some of the original equipment that manufactured the product in the late 1800's.
A package of Sen-Sen Breath Fresheners /// Sen-Sens were available in small packets or cardboard boxes. Similar to a matchbox of the time, an inner box slid out from a cardboard sleeve revealing a small hole from which the tiny Sen-Sen squares would fall when the box was shaken. Sen-Sen's ingredients were licorice, gum arabic, maltodextrin, sugar, and natural and artificial flavors.
