These bottles will hold between 20 and 40 drops.
You can use a plastic pipette, or glass dropper to fill the bottle. After you have added your oils to the bottle make sure to press firmly on the reducer. This will help avoid leaking. Bottles containing oils or liquid should be stored and transported upright to prevent leaking. Once all the oil is in and the cap is screwed on, you will want to label the vial so you know what it contains.
This item is sold in bags of 24 vials, reducers and caps or in flats of 144.
