Be careful of the liquid volume of your order. I have around 17 orders of their essential oils in 2 oz amber glass bottles. Those 2 oz bottles are as expected, top grade concentrate. However, recently I purchased 16 oz quantities of a couple oils, they arrived in aluminum metal cans. These 16 oz "essential oils" were highly watered down versions of their 2 oz package counterparts. The strength was approximately only 1/3 of what they should be. This is a dishonest practice and they have lost a customer.
