The Serendipity Hybrid Pen is a collaborative pen between James Finniss of Pensive Pens and Robert Oster. The Serendipity is a hybrid between a dip pen and a fountain pen where it functions without a filling mechanism and only operates with whatever ink is in it from dipping the pen. Because, however, it has a standard #6 nib and feed it will hold a lot more ink than a dip nib, even one with a reservoir. Lake of Fire is a new ink in the same colour family as Fire & Ice from Robert Oster's new line of InkArt inks. It came bundled with the Serendipity pen for the first 50 purchasers (but won't be released until later in 2017 on its own).
