The tasteful Buttercream aroma evokes a mouthwatering recipe of rich and creamy vanilla. To use the fragrance fan, insert the included D size battery and the fragrance refill, then switch the unit to the "on" position. The portable scent diffuser quietly begins spinning its blades, diffusing the scent throughout the room. Fan was designed to look like a Yankee Housewarmers® jar and operate with no plug or flame, making it safe to use virtually anywhere you could imagine. Made in the USA.
