A beautiful and infinitely refillable writing pen with a Japanese-made writing tip. Simply dip the cotton core reservoir into your chosen fountain pen ink to refillno mess, no waste. Buy two (or more!) Wren pens and save 10%.

Each year, an estimated 9 billion pens are thrown away. The Wren was designed to break that cycle. Built to last a lifetime, it lets you refill with ink whenever you need it, eliminating the frustration of disposable pens piling up in drawers.

How to use: Unscrew the barrel, dip the cotton core into your favourite dye-based fountain pen ink, and you’re ready to write. A single fill writes consistently for 344 metresthat’s roughly 50 A4 pages of handwriting.

Compatible with all standard dye-based fountain pen inks (avoid shimmer or particle-based inks). When the Japanese-made tip eventually dulls after months of use, replacement tips are available in packs of three.

Includes: The Wren pen, Japanese-made writing tip, 3ml Midnight Ink sample, and ink reservoir.
