Can you please make the bottles clear or maybe even a see through light green, just so we can see the amount of oil left in the bottles. Nothing worse than going to use the oil and find no oil left. Love how the oils come in all different sizes and the variety of oil. It would be good if you sold oil burners (in different sizes), tea candles and aromatherapy books or if the staff had a background with some knowledge of oils and how they can be used.... more than just cleaning. I've been using your oils when you only did eucalyptus oil. Keep up the good work.
