The StarWalker PolarGreen collection brings the beauty of the Northern Lights to life. On Earth, humans can gaze skyward and be transported to realms of wonder as they witness their grand spectacle. The dome on the cap top is made of transparent resin and glows in low light, recalling the enchanting dancing auroras of the night sky. The wave pattern on the dark green precious resin of the cap and barrel admirably captures the spectral sheen of the lights, and the matte finish accentuates the seemly reflections. The Fountain pen features platinum-coated fittings. The meticulously hand-crafted Au585/14k gold nib displays an elegant rhodium coating.
