Widely known as the BEST natural diffuser available today! Why? The Banksia Grandis seed pod (the material from which they are made) is particularly porous, it soaks up your essential oil and slowly releases the aroma through its pores. No flames and no electricity are needed with our all natural diffuser! Your aroma pod comes pre-tested and filled with our very own high quality Pure Australian Eucalyptus oil. Each one is completely different from the last and can be filled with any essential oil you like. Aroma Pod Instructions Step 1. Remove the cork from Aroma Pod Step 2. Choose a good quality Essential Oil or blend and place 3-4 drops into the pod Step 3. Place cork back on Aroma Pod The aroma should last up to 4 weeks - add a few extra drops of essential oil weekly, for a longer lasting effect.
