Made with no DPG our unique base will provide you with a great scent throw using our ratan reeds. Use 70%/80% base to 30%/20% fragrance oil to start and adjust up or down according to your own personal needs. Use a narrow necked glass vase or bottle, add about an inch of your fragrance oil, base mixture then add the desired number of reeds into the neck of the vase or bottle. The reeds will begin to soak the oil up the shaft and into the air around it. It may take few hours to achieve maximum strength. You can shorten this time by turning the reeds over and reinserting them in the bottle after an hour or so. Start with 6 reeds and add more if a more intense aroma is desired! Flip reeds any time you notice fragrance diminishing. These are just like candles, you need to test to find what fragrance, base combination will get the maximum results.
