Wearingeul Converter Set

Three piston converters, sized for standard international fountain pens built so your Wearingeul Preface pen can run any bottled ink, not just cartridges.Each one fills with a simple twist of the piston knob and comes capped in silicone for clean storage between uses. Keep one in your daily writer, one loaded with whatever Monthly World Literature shade you’re testing, and a spare on hand. A quick-reference guide is included for first-time filling and cleaning.
