1. Transfer oil from another vial or mix a blend of your own in this bottle. You can do this easily by using a plastic pipette syringe or glass dropper. The opening of this vial is large enough that you can also carefully drip oil into it from your essential oil bottles. (Again, for best results dilute essential oils with at least an equal amount of carrier oil.)
2. After the oil is in the bottle, place the rollerball insert in the opening. Press the insert down firmly until securely connected (try to not push directly on the roller ball itself). Be careful and hold tightly to the bottle during this process.
3. Please note that roll-on bottles containing liquids should be stored and transported in an upright position to prevent leaking. (We cannot be responsible for damage or loss caused by leaks.)
4. Once the oil is in the vial and the roller ball is inserted, you may want to attach a label. (Be sure to wipe off any oil from the outside of the bottle before labeling.) You can purchase our preprinted circle labels for all dōTERRA^® oils and blends. Or you can print your own blank, white circle labels.
