The Moonmen Sea One Fountain Pen

Mike astrick's list includes four different inks: Hellb z blue, black, pilot, o roshezuku. The moonmen sea one is as simple as it gets, but looks great and works flawlessly. It represents the basic elements of a fountain pen - all components are clearly visible. Everything is simple and not overly engineered, except for the shut off valve in the opus 88 demonstrator.
