Opus 88 Demonstrator Eye Dropper Clear Fountain Pen

Opus 88’s Demonstrator is a large, translucent fountain pen that lets you see your ink in action. Designed with a rare eyedropper filling system and a built-in shut-off valve, it offers generous ink capacity and precise control, making leaks and burps a thing of the past. You fill the barrel directly using the included glass eyedropper or a syringe. For longer writing sessions, simply twist open the valve to allow ink to flow; close it again when you’re done for safe transport. It’s a clever blend of traditional technique and modern functionality.
