This dropper cap allow you to control essential oil flow when applying, transferring, mixing, or diluting oils or blends. Fits perfectly on a 2 oz. amber or blue glass bottle and on other bottles with a 20-400 neck size.

  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. You can purchase our blank labels to customize and print yourself.
