Neroli and Pomegranate Reed Diffuser Kit. Reed diffusers are a highly effective way to impart fragrance into a room. Providing a constant scent and without the vigilance needed for a candle, diffusers are an ideal solution. Simply put, a totally addictive combination of orange blossom and sweet pomegranate. Simply put the wooden tapers into the oil bottle and allow the fragrance oil to rise up the reeds by capillary action, and evaporate into the room. Turn the sticks every now and again for more fragrance. The fragrance lasts approximately 10-12 weeks depending on ambient temperature and airflow. Refills are also available.
