Omas Extra Lucens Black and Gold Celluloid Fountain PenThe Extra Lucens, originally created in the 1930s by Armando Simoni, introduced a revolutionary 12 faceted design and roller clip that set a new standard for the Italian writing industry. To complement this masterpiece, Omas uses only the finest celluloid. The modern refilling mechanism was ingeniously designed to ensure that ink never contacts the celluloid, preventing corrosion and preserving the pen's quality for years to come.
