The David Oscarson Celestial collection captures the mysteries of the heavens in hand-engraved guilloched silver or gold, and multiple colors of hard enamel. A profound testament to the artisan's eternal quest for perfection, these heirlooms promise to endure as long as the cosmos itself. The fountain pens feature iridium-tipped 18K gold nibs coupled to an ebonite feeder; a unique filling system designed to accommodate a cartridge, converter, or eyedropper fill provides exceptional flexibility for use. Five breathtaking color variations are available, each limited to a series of 88.
