Platinum Century Rhodium Black Diamond Fountain Pen

The Platinum #3776 Century Rhodium Black Diamond fountain pen combines Japanese craftsmanship with functional engineering. This writing instrument features a 14-karat gold nib with iridium tipping, available in fine line width producing 0.28-0.34 mm strokes. The pen utilizes Platinum's patented Slip and Seal mechanism that prevents ink from drying for up to 24 months when capped. Constructed from dark green translucent resin, the pen measures 139.5 mm in length when closed, with a diameter of 15.4 mm and weighs 24.6 grams. Rhodium-plated elements include the clip and decorative rings, while the nib also receives this corrosion-resistant plating. The cap features a threaded design for secure closure. The #3776 engraving on the cap band and nib references Mount Fuji's elevation of 3776 meters, Japan's highest peak. This fountain pen accepts standard international cartridges and is compatible with Platinum's converter system for bottled ink use, though the converter is sold separately. Each pen is handcrafted and presented in an elegant gift box, accompanied by a blue-black ink cartridge. The design emphasizes durability and writing reliability with a balanced weight distribution suitable for extended writing sessions.
