Product Overview
The Opus 88 Demonstrator fountain pen, available in Sapphire, features a distinctive design and practical features. It is a large non-postable pen filled via eyedropper, equipped with a piston-operated shut-off valve.
Its design includes a blue acrylic grip section and barrel, accented with a clear blue resin finial and end cap, accompanied by a sleek gunmetal clip and a black stainless steel #6 JoWo nib.
Additionally, it comes with a glass eyedropper for ink refills, ensuring smooth writing experiences.
An ebonite piston and rubber gasket prevent leakage and burping by sealing the feed off from the barrel when fully depressed. Unscrewing the blind cap and loosening the rod at the rear of the barrel regulate ink flow to the feed, while the shut-off valve can be left open during extended writing sessions for maximum ink capacity utilization.
The pen's opaque body design does not compromise functionality, offering users an efficient and stylish writing instrument.
