Wren - Take Flight & Write

Writing Instrument of the Year 2025, Stationery Awards, London

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
  • Pen barrel diameter – 13mm
  • 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 standard Fountain Pen Inks and we have a beautiful range of colours, which are perfect for the Wren and can be found here. Please note the Wren is not suitable for use with our Shimmer Fountain Pen Inks, No.60 Pigment Black Ink or Calligraphy Inks.

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.

I have dyslexia. My handwriting is not the best. I have no idea why but when i find the right pen my handwriting improves immensely. This is the right pen. So smooth. It is a pleasure to use. I usually avoid handwriting but now im looking for any excuse to use it. Thank you

Wren right off

Already a fan of my Wren but couldn’t resist another. Writes really nicely and most importantly gets rid of disposable plastic. I write a lot abd used to get through hundreds of plastic pens. I bottle of ink has lasted over a year with these pens! Save the planet and enjoy a fantastic pen !

A fabulous, fun and beautiful writing tool for art or for evetyday. It was a long shipping time from the UK to Boston, Massachusetts, but worth every second. ~ Jeanette G at Jega Art, 2025.

Love the Wren. Feels good in the hand, is a great size, and ink lasts at least two months with daily writing. I've already worn down one tip, but I did have the foresight to order extra. I have a feeling that will be the thing I'll have to replace the most frequently, but I still love the way it writes. Wish there was an optional clip sold separately to secure it in my pocket or attach it to a notebook, that would make this pen even better!

The pen you didn’t know you needed

I’d always wanted to start writing again but kept putting it off—until I came across this pen.
