These fragrance oils have more essential oils added but are still synthetic fragrance oils so incense sticks/cones have the benefit of the essential oils with the safety of the fragrance oil. Pure essential oils can be hazardous to kids and/or pets when burned so we do not use straight essential oils in candles/wax melts/incense, but every fragrance oil has a touch of essential oils in them, these just have a bit more! Lighter scent throws are to be expected since that is the nature of essential oils when burned. Essentials of Eve Incense Collection is made of 10" incense sticks and incense cones! These are available in all 8 varieties in the Essentials of Eve line. Each 10' stick burns for approximately 45 minutes.
