PLATINUM Piston Converter (For Platinum Only)

The Platinum Piston Converter PQ-500 is a high-quality ink converter designed to turn compatible Platinum cartridge-based pens into piston-fill fountain pens. With a capacity of about 0.5 ml, the converter allows you to draw bottled fountain-pen ink directly into the pen using a smooth twist/ plunger mechanism, offering significantly greater flexibility and colour choice compared to disposable cartridges. Made of durable plastic (with metal or gold-accent fittings on some variants), it ensures reliable ink flow and a snug, secure fit for most Platinum fountain pens. By using this converter, you can refill your pen repeatedly with any bottled ink — making writing more economical and environmentally friendly than frequent cartridge replacements.
