A 250 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 Lemon Lavender, a citrus and herbal fragrance. Zesty lemon meets soothing lavender, with herbal notes in the middle and a hint of spice in the base, a balance of fresh and relaxing. Reeds are not included. Keep the oil away from children and pets and wipe up spills straight away, as it can mark polished surfaces.
