Abstract: A deodorant system includes a substantially hollow, elongated housing open at either one or two opposing ends. The housing includes a peripheral wall that has at least one slot therethrough, the peripheral wall preferably including a front wall, a rear wall, and two opposing side walls that each includes one of the slots. A piston is slidably retained within the housing and has a cartridge attachment mechanism on a first and optionally a second side thereof. An actuator projects through each slot of the housing and is selectively positionable along the slot to position the piston within the housing. An interchangeable deodorant cartridge has a rigid base with a cooperative cartridge attachment mechanism on a bottom side thereof for attaching to the cartridge attachment mechanism of either one or two sides of the piston. A top side of the rigid base is fixed with a deodorant material.
