Do you need to replace a cap on one of your essential oil vials? This white cap fits standard 5, 10, 15, and 30 ml (1 oz.) bottles. Euro-style means that a built-in orifice reducer snaps into place when you first twist the cap onto the vial. This helps control by drops the amount of oil you dispense. The vial is also sealed until you twist the cap off for the first time.

Note: From one package to another, caps may vary in outward style and orifice reducers may vary in height.

Contents: 1 Euro-style cap.

Neck: 18-415. Fits 5, 10, 15, and 30 ml (1 oz.) glass bottles.

  1. Transfer oil from another bottle using a plastic pipette, syringe, or bottle dropper.
  2. Once the vial is filled, twist the euro-style cap onto the top (clockwise). As the cap tightens, a faint popping sound will indicate that the orifice reducer has dropped into place and is ready for use. The cap is also equipped with a seal (like that of a water bottle) which will break when opened.
  3. With the cap in place, the vial is ready to be labeled. You can purchase our blank labels to customize and print yourself:
