Sen-Sen was a type of breath freshener originally marketed as a "breath perfume" in the late 19th century by the T. B. Dunn Company^[1] and then produced by F&F Foods until they discontinued the product in July 2013.^[2] Sen-Sen bore a strong similarity to Vigroids, a liquorice sweet made by Ernest Jackson & Company, Ltd.

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.^[2]

Sen-Sen's ingredients were liquorice, anise, gum arabic, maltodextrin, sugar, and natural and artificial flavors.
