The Ashleigh & Burwood Scented Home Reed Diffuser 300ml Refill Bottle for refilling you Scent Home Glass Bottle diffuser. Choose from fragrances ranging from sweet and floral to spicy and woody. We recommend changing the reeds with each new bottle of fragrance. This is because the reeds can become clogged with fragrance and dust, stopping them from working efficiently. What do they smell like? MOROCCAN SPICE: Exciting aromas of a hot Moroccan souk combine with a rich blend of warm honey, orange and nutmeg scents. Base notes of sandalwood, agarwood and resin add an earthy depth. HOW LONG WILL THEY LAST: Reed Diffuser refiill will last up to 6 months. This can vary based on a variety of factors, such as airflow, ambient humidity, ambient temperature and the number of reeds used.
