A beautiful and infinitely refillable fineliner, writing, and brush pen, including 9 professional artist's tips and 2 writing tips. Every year, millions of disposable pens are thrown-away, adding to the growing environmental waste. Tom thought it was about time to tackle one of the biggest culprits: the everyday writing pen. The result? The Wren—a pen designed not only to write beautifully but also to last a lifetime, helping to reduce the mountains of waste created by disposable pens.

Tom crafted his first pen from Corian and brass on his father-in-law’s vintage lathe, and the journey began. He reinvested every profit into improving his products, all while nurturing a community of artists and creators who supported his journey and kept sustainability at the front of his mind at every decision. Each pen is designed by Tom himself, and we work with a select group of manufacturers from around the world, some with over a century of experience in their craft, to source the finest components, including nibs, inks, and tips.
