If you have any of our 3mL, 5mL, or 12mL bottles, their lids and rollers are interchangeable.

1. They can be converted to roller bottles with the roller top and lid. Place the roller inside the lid and twist them onto the bottle together for an easy assembly. If there is a tap applicator in the bottle, this must be removed first.

2. If your bottle arrives with a roller and you would prefer a have a twist lid instead, this is useful for long-term storage. You can choose a tap applicator with it (only a drop comes out at a time)

3. Or you can order the twist lid with a pipette to transfer oil from the open bottle into another vessel or a diffuser. We will include a mini pipette with this option.
