All fragrance oil sales are final. Due to health and sanitary concerns, and to protect the integrity of our oils, fragrance oils are non-returnable, non-refundable and non-exchangeable. We recommend purchasing sample sizes to ensure that you (or your customers) like the scents and that they perform properly in your applications before investing in larger sizes. Note: Fragrance oils can best be judged when used in an actual application and not directly out of the bottle. No warranties are expressed or implied.
