About This Product
This International Standard converter allows your MD Fountain Pen — or many other compatible pens — to accept bottled fountain pen inks. Made for Midori by Schmidt, the German pen manufacturer, it's a sturdy and mechanically simple piston converter that seats securely in your pen.
Never used a fountain pen converter? Here's how: insert the empty converter like a cartridge into your fountain pen. Twist the piston all the way down, dip your nib into a bottle of fountain pen ink, then twist the piston all the way up to fill the converter.
