All the old bird may have already know this. I just found out today so just sharing with those that does not know.
For vivi nova, there is a small plastic tube inside the plastic drip tip. Take it out.
Open up the top cap for vivi nova, and place it inside the rubber tube at the head.
slowly close back the top cap and insert ur fav drip tip or the plastic 1.
*this will prevent leaking when it is turn upside down and also no more condensation inside the top cap in between your drip tip.
