Three layers, laser welded together. Delivers an architect-like line, with adjustable line width, designed to emulate the writing experience of a brush, extremely suitable for artists. · Featuring three stacked steel nibs · EF – 4B · Ebonite feed and housing, JoWo #6 Screw-in compatible · Standard international converter compatible · Individually handcrafted The saying goes that necessity is the mother of invention – and without my desire for a Nagahara King Eagle, the Regalia Trilogy would not exist. This nib is incredibly versatile, seamlessly transitioning from an EF to a 4B depending on the user’s writing angle, eliminating the need for the writer or artist to have to stop and swap out instruments. You might begin to notice this feature across many of my nibs; it isn’t just efficient, but I believe it offers good value for an artist to be able to use one tool for the job without needing to pause or break. Whether the lines need to be thick or thin, deliberate or brush-like, the Trilogy is there for the job. Multi-layered.
