The same wonderful essential oils that are infused in each blend are also available to refresh your potpourri at a future date. Use the glass eye dropper to spruce up the fragrance just before a party, or toss the potpourri in a plastic bag with the entire bottle of oil. 1 oz. Our unique and deeply aromatic blend of French lavender & Italian rosemary is enriched with the zest of bergamot & a few drops of English Amber.
