This .5 ounce amber glass refill bottle contains enough fragrance oil for about 2-3 refills for our Boho wooden top diffusers. The selected refill fragrance should be the same as what was used for the diffuser that is being refilled. If you change scents, it is best to stay in the same family of scents (for instance, fruity or floral, etc).
PLEASE NOTE: These are to be used ONLY in our Boho diffusers. They cannot be used in essential oil diffusers.
