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 Clean Cotton, a fresh fragrance. The scent of sun-dried cotton with fresh greens, white flowers and a hint of lemon. Top notes are ozone, leafy greens and bergamot, the heart is lily of the valley and rose, and the base is vetiver, cedar, musk and soft woods. Reeds are not included. Keep the oil away from children and pets and wipe up spills straight away, as it can mark polished surfaces.
