Essential: A basic thing that you cannot live without. With that in mind, the Essential was designed to be a slim, simple, great writing instrument. The Forest Night Essential uses a star-night finish on the band and black coating on cap and barrel to present a silent and relaxing night view as if looking up to the night sky from inside the forest. Pen comes equipped with a Schmidt 888F smooth writing rollerball refill, suitable for everyday writing on most papers.
