Sample vials for essential oils are an absolute necessity for those who are going to be starting their own essential oil based business. Small brown sample vials allow consultants to share individual essential oils, as well as essential oil blends, with potential clients and new customers. The smaller size of the sample vials provides the recipient with a “taste” of an essential oil they are interested in. This is a win-win situation for both parties as it prevents waste and ensures users are able to determine which essential oils work best for them. Sample vials are manufactured from dark glass, may or may not have an orifice reducer attached, and small color coded stopper dots to identify which sample is stored within.
