Wren - Take Flight & Write

A beautiful and infinitely refillable writing pen, equipped with a Japanese-made writing tip. We're on a mission to make choosing refillable options easier, so you can now buy two (or more!) Wren pens and save 10%

Each year, an estimated 9 billion pens are thrown away, contributing to growing environmental waste. Many writing tools are designed with convenience in mind, often leading to a cycle of frequent replacements, which generates significant waste and limits options for those seeking more sustainable, long-lasting choices.

As a product designer and craftsman who loves writing, I became frustrated with the waste created by disposable pens. They would pile up in drawers, waiting for a specific refill, or worse, end up in the bin despite being perfectly usable – if only they had ink.

After years of designing and handcrafting calligraphy and fountain pens for creatives worldwide, I decided it was 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.

Included in the box:

  • The Wren in your choice of colour
  • Japanese-made Writing Tip*
  • 3ml Midnight Ink sample
  • Ink Reservoir

*0.3–0.5 depending on pressure

Specifications:

  • Length capped – 80mm
  • Posted (cap on the end of the pen) – 120mm
  • Weight – 20g
  • Made from Anodised Aluminium

Full FAQs and a video guide to getting started with your Wren can be found here.

What ink can I use?

The Wren is compatible with all but the most experimental fountain pen inks (think shimmer + iridescent). We offer a beautiful range of ink for fountain pens, which are perfect for the Wren and can be found here.

Note: Calligraphy Ink has an acrylic binder which will block the pen and is not suitable for use with the Wren.

Some ink colours can concentrate in the tip, so you may experience a lighter colour after a line or two. This is completely normal and looks quite nice!

How do I store the reservoir and tips?
You can store reservoirs and tips, and change to a different colour using spare reservoirs and my reservoir storage containers.

How long will the tips/ink last?
You can expect the high-quality, Japanese-made tip to last for months of use. We tested a single ink fill in the Wren on a plotter – a device used for precision drawing – and it wrote consistently for 344 metres. That's the equivalent of 50 A4 pages of handwriting!

When the tip eventually dulls, you can find packs of three replacement tips here.

Anything else I should know?
Yes! I’ve designed the pen to include ‘micro-grooves’, tiny ridges that enhance grip without using plastics. Please note: the black and midnight colourways do not feature these micro-grooves, as they have a grippy matte finish.

We aim to process your order within 1-3 working days. Please note that this increases to 1-4 working days for orders that include any personalisation, such as engraving.

To unwrap my order of the Wren with its accessories was a joyous event on its own. So beautifully wrapped. It felt like a gift in stead of an order. I’ve tried one ink thus far and is gorgeous. Plan to try the others soon! The Wren dances over the paper, smooth and wonderful! It’s a joy taking notes now 😊. In the nearby future I hope to order the Lumos as well and take up long lost calligraphy again. Thank you for your wonderful design. I love it!

Capped it's short enough to carry easily in a pocket, it writes smoothly, I'm delighted with it. I just wish someone had invented this years ago!
