Instructions:

• Transfer oil from another vial or mix a blend of your own in this bottle. You can do this easily using a dropper(included). The opening of this vial is large enough so that you can even carefully drip oil into it from your essential oil bottles.
• After filling the bottle with oil, insert the roller ball in the opening. Press the insert down firmly until securely connected (try not to push directly on the roller ball itself ). Be careful, and hold tightly to the bottle during this process.
• Once the oil is in the vial and the roller ball is inserted, you can attach a label(included). (Be sure to wipe off any oil from the outside of the bottle before labeling.)

NOTICE ABOUT THE OILS:

Original essential oils need to be diluted before using. And the dilution should be within a proper ratio. If the oil is too thick, the roller balls may get clogged and thus not work well; while if the oil is too thin, the bottles would leak slightly.
