Attach to Oliviers&Co olive oil tin for a drip-free drizzle (adapted to 250ml, 500ml and 1L tins) ! Reusable and handy, this spout helps your olive oil stay fresh to the last drop. How to open the olive oil tin and attach the spout: 1. First, you have to make sure the original pourer is fully extended. Look for the little arrow in the green top that is flat and flush to the tin. Lift the ring that the arrow points to and slip your finger through it. Gently wiggle the top up until it is fully extended, about an inch from the top of the tin. 2. Remove the green screw-off top and replace it with the new green spout. 3. Twist on the spout until it is tight and flush to the tin top. 4. Pull open the attached little cap and you are ready to pour!
