Note: To prevent deterioration of the rubber bulb—particularly when using myrrh or citrus oils—store bottle in an upright position and replace the dropper cap with a regular cap when not in use.

Neck: 24-400.

Size: Fits our 4 oz. blue glass bottles.


  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.
