Each diffuser is made from a Banksia Grandis seed pod which is a naturally porus material so makes a fantastic natural diffuser! The pod soaks up the essential oil and slowly releases it through the pores.
Any fragrance can be used in the aroma pod, just wait for the current oil to completely dissipate before removing the cork and adding 1ml of a high quality essential oil of your choice. This process can be repeated many times. The scent should last for about 2 weeks but feel free to top up a drop or two of oil weekly for a longer lasting scent.
Each aroma pod comes filled with a high quality Pure Australian Eucalyptus oil and has been tested to ensure it doesn't leak. However, as it is a naturally porus material it is highly recommended to place the aroma pod on something to protect surfaces.
Measurements: The mini aroma pod measures approximately 7cm in circumference and the medium aroma pod measures approximately 9cm in circumference.
None of the Banksia Seed pod products are treated at all.
