Introducing the Opus 88 Clear Demonstrator Fountain Pen, a one-of-a-kind writing tool that stands out from the rest.

This generously sized pen cannot be posted and employs an eyedropper filling system with a piston-operated shut-off mechanism. Its design showcases a striking interplay of frosted and transparent resin, creating a visually captivating aesthetic. Complementing its appearance is a refined black clip and a silver stainless steel #6 JoWo nib.

The package includes a glass eyedropper for effortlessly filling the pen with your preferred ink. Please note that JoWo is in the process of updating its nib design, moving away from the older scroll pattern to a more streamlined look. Due to this transition, the current stock is a mix, and the received product might differ from the photographed version.

This pen can be filled directly with bottled ink by unscrewing the grip section and filling the pen with the included eyedropper. The piston knob at the back of the pen is not used for filling the pen. Instead, it controls a safety shut-off valve that prevents the pen from leaking when not in use. When using or filling the pen, unscrew the knob and draw back the piston to allow ink to flow into and out of the pen. When the pen is not in use, screw the knob down tightly.

For enhanced functionality, the pen incorporates an ebonite piston and a rubber gasket. When fully depressed, these components seal off the feed from the barrel, significantly minimizing the risk of leaks or ink splatters. To facilitate ink flow, simply unscrew the blind cap and slightly loosen the rear rod of the barrel. This configuration is especially useful during extended writing sessions, as it allows the shut-off valve to remain open, capitalizing on the pen's substantial ink capacity.

With its completely transparent body, you can effortlessly monitor your ink level and observe your nib even when the pen is capped.

Experience writing in a whole new way with the Opus 88 Demonstrator Fountain Pen.
