The bottles are very tiny and not well labeled. I don't even know the bottle size because it doesn't say. They say 100% essential oil and other oils so I don't know if they are safe to use directly on the skin, or if I need to mix with a carrier. Three of the bottles are custom blends, but there's no description of what is actually in the bottle. Even a card with information would have been helpful. There was nothing. Canceling.
