Description The Sailor Special Nib 1911 Large fountain pen with the 21k Cross Concord nib is only available for purchase in our physical store. The Cross Concord nib is part of the 2019 relaunch of the Special Nib Program. The Sailor Special Nib Cross Concord nib is a double-layered nib with unique cross point design on the tipping that comes from layering one nib directly on top of the first nib. When you look at the nib from the front, the space between the 2 nibs, and the nib slit of the 2 nibs together forms a cross. When used in the normal writing position, the line is fairly thin, and when inverted (upside down), the nib provides a broad calligraphic stroke that is very wet and juicy. For the best long-term performance of your Sailor fountain pen, we highly recommend that you use the Sailor Fountain Pen Maintenance Kit for the most efficient way to clean your fountain pen!
