Comment on any olive oil bottle for drip-free oil! Reusable and easy to use, this spout helps keep the olive oil fresh until the last drop. How to open the olive oil bottle and attach the spout: 1. First, make sure the original pourer is fully extended. Look for the small arrow on the flat green top that flows into the tin. Lift the ring indicated by the arrow and slide your finger through it. Gently shake the top until it is fully extended, about one inch from the top of the bottle. 2. Remove the green screw cap and replace it with the new green spout. 3. Turn the spout until it is tight and secure on the top of the can. 4. Pull the small cap with its opening, and you will be ready to pour.
