Montegrappa Extra Otto – Celluloid “Malachite

The Montegrappa Extra Otto “Malachite” is a masterpiece of Italian craftsmanship, combining timeless elegance with the distinctive octagonal design that characterizes the Extra Otto collection.

Available in both fountain pen and rollerball versions, this writing instrument showcases the finest materials and artisanal excellence from Montegrappa’s historic atelier in Bassano del Grappa, Italy.

Crafted from genuine celluloid in the stunning Malachite pattern, this pen exhibits rich green and black tones with a deep natural sheen. Celluloid is one of the rarest and most prestigious materials ever used in fine writing instruments, and Montegrappa is the only manufacturer that still possesses authentic celluloid stock.

Each pen features solid sterling silver trim, ensuring durability and luxury. The fountain pen version includes an 18K gold nib and piston filling system, while the rollerball version offers smooth and effortless writing performance. The feeder is made from ebonite, renowned for its superior ink flow and responsiveness.

Presented in its original elegant Montegrappa walnut wood box with documents.

A true collector’s piece and a remarkable tribute to Montegrappa’s heritage of artistry, precision, and Italian excellence.
