The Yankee Candle Signature Reed Diffuser gives continuous, flame-free fragrance to a room. The set is a 100 ml glass bottle of fragrance oil with a ceramic cap and seven natural rattan reeds: take off the cap, put the reeds in the bottle and the oil travels up the reeds and scents the air. It suits small to medium rooms, bathrooms and passages where a candle is not practical. 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. Turn the reeds now and then to refresh the scent, and keep it out of reach of children and pets and off polished surfaces.
