100% strength of essential oils??
These don't seem to be pure essential oils. More like diluted blends of essential oils They are not strong at all in a diffuser. I didn't return because they are nice blends that  I  can use directly on my skin. Some of the ingredient labels don't really match the scents either. I have used essential oils for over 20 years and am familiar with a lot of the scents.
