We are introducing better packaging etiquette. You know our lovely eco-felt envelopes? Well now, each time you receive one in the mail to keep your cleansers and hydrosols cool and fresh, you will also find an envelope stamped and addressed back to us. Unless you wish to keep your eco-felt envelope, you can place it (along with the twine if you wish) in the addressed envelope and mail it back. I'll keep it for you for the next time, repair it should it so require, and send it back to you with your next order, with another stamped envelope--and a $5 credit toward any oil of your choice--to use or accrue, it is entirely up to you. I know my customers are environmentally conscious and don't need an economic incentive, so please don't think of it as such, but rather as a way of using our collective resources more efficiently.
