Description The Sailor Pro Gear fountain pen named Stellar Black Hole is inspired by and named after a phenomenon that creates widespread wonder and fascination: the Black Hole. The resin body and finial are space black with various sparkles to look like an explosion of extraterrestrial dust, and the cap is a warm golden yellow with golden glitter to appear like stars across the surface. The Sailor Stellar Black Hole has a gold clip and trim, and the bi-color 21k nib is available in all standard nib sizes. The Sailor Pro Gear fountain pen includes a proprietary Sailor converter for use with bottled ink, as well as 2 Sailor proprietary cartridges. 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!
