A 200 ml refill bottle of fragrance oil for Yankee Candle Signature reed diffusers. Top up your existing diffuser bottle when it runs low, so you can keep the same scent going or switch to a new one without buying a whole new set. For the best result, put fresh reeds in when you change to a different fragrance. This one is Black Cherry, a fruity fragrance. Ripe, juicy cherry with almond at the top, cherry and a touch of cinnamon in the heart and a sweet cherry base. Reeds are not included. Keep the oil away from children and pets and wipe up spills straight away, as it can mark polished surfaces.
