  1. To use the dropper, simply squeeze and release the rubber bulb to draw the liquid up into the glass pipette. Then gently squeeze the rubber bulb to apply the liquid a drop at a time.
  2. Simply transfer oil from another bottle. You can do this easily by using a plastic pipette, syringe, or glass dropper.
  3. Once all the oil is in and the dropper is screwed on, you may want to label the bottle.
