Quick science fact: a stellar black hole is formed by the gravitational collapse of a massive star’s core after a supernova when it exceeds the Tolman–Oppenheimer–Volkoff limit (or the upper limit for the mass of a cold, self-gravitating body). Inspired by this cosmic explosion that occurs during a massive core implosion, the Sailor Pro Gear Stellar Black Hole features a black body paired with a warm yellow cap, both of which are dusted with glitter representing faraway stars. A beautiful homage to the violent forces that shape the universe, it is tipped with Sailor’s popular 21-karat gold nib for a unique writing experience. 

We have for sale a brand-new Sailor Pro Gear Midnight Sky with gold-plated trims and a two-toned nib in M. It comes complete with its box, papers, and other inclusions.
