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 Sage & Citrus, a herbal citrus fragrance. Earthy sage with soft talc and lemon-lime. Top notes are herbal, lavender and citrus, the heart is geranium and lavender, and the base is patchouli, powdery notes, musk and woods. Turn the reeds now and then to refresh the scent, and keep it out of reach of children and pets and off polished surfaces.
