New Car. The Mr&Mrs Fragrance Niki car air freshener celebrates the good life and unmistakable Italian style. It combines aesthetics and functionality in a premium, refillable product. The figurine's refill is made from porous, non-toxic EVA (rubber), saturated with a fragrance oil containing active odor-absorbing molecules that, when exposed to air from the car's vent, releases a pleasant fragrance for up to 45 days. Once depleted, the refill can be easily replaced with the same or a different fragrance.
