Opus 88 Demonstrator - Sapphire

The Opus 88 Demonstrator Sapphire fountain pen makes a bold impression with its sparkling, swirling acrylic resin in a rich sapphire blue. Its clean, cylindrical profile with flat ends highlights the modern demonstrator design, while a JoWo #6 steel nib finished in black PVD delivers smooth, dependable writing performance with a sleek, contemporary look.

This pen features Opus 88’s signature eyedropper filling system, offering an exceptionally large ink capacity. To fill, simply unscrew the grip section, use the included pipette to add ink, and reassemble the pen. Before writing, the rear blind cap must be loosened to open the internal valve. This shut-off valve system allows you to control ink flow—open it for extended writing sessions and close it when traveling or storing the pen—providing both convenience and peace of mind in everyday use.
