The Aurora Optima Black with Gold Trim is the most classic colorway in the Optima lineup — a deep black Auroloide body with warm gold hardware that's been a benchmark of Italian pen design for decades. The 14k gold nib and piston filling system make it as functional as it is iconic, and the black Auroloide has a depth and warmth that distinguishes it from ordinary black resin.Specifications Brand: Aurora Model: Optima Black Color/Finish: Black Auroloide Filling system: Piston (built-in) Nib material: 14k Gold Nib sizes available: Extra Fine, Fine, Medium, Broad Body material: Auroloide (Aurora proprietary celluloid-like material) Trim: Gold-tone Made in: Italy Nib Guide Extra Fine — Very narrow line; ideal for small script or fine-lined paper Fine — Narrow, precise line; excellent for small handwriting and detailed work Medium — Balanced everyday line width; smooth and versatile Broad — Wide, expressive line with excellent ink shading Free shipping on all U.S. orders.
