Meet the Wren – Write Off: the infinitely refillable pen that gives disposable pens another life. An estimated 9 billion disposable pens are thrown away globally each year. It’s a staggering number. Having spent years creating pens designed to be reused for a lifetime, I couldn't help but feel for these poor little pens – destined to be buried for millennia. It was time to close the loop – to find a way to repurpose them and give them a brand-new life.

Enter the Wren – Write Off, my boldest project to date. Over the past year, we've been working with schools and organisations to intercept stationery waste at the source, preventing it from reaching landfill. This precious plastic is then meticulously separated and sorted to create the wonderful colours you see before you.

Crafted in collaboration with the brilliant Brothers Make, each lid is made by chipping, injection-moulding and hand-finishing the reclaimed plastic – a process that’s more artisan than assembly line. This unique method means every lid is completely one-of-a-kind.

This isn’t just a pen – it’s a small act of rebellion against waste, and a celebration of creativity.

We're on a mission to make choosing refillable options easier, so you can now buy two (or more!) Wren pens and save 10%

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! Each lid is completely unique, made using a one-of-a-kind blend of upcycled plastics. That means colour density and placement will vary from pen to pen. Some are bold and bright, others more subtle – it’s all part of the charm. Think of it as a lucky dip for your desk. No two lids will ever be the same.

Here’s the how (and why)

Waste Plastic: Reimagined

Every year, billions of plastic pens are thrown away – we wanted to do things differently. By collecting waste from local schools and organisations, we’ve reimagined what a pen can be: thoughtfully made, built to last, and crafted with care from reclaimed plastic.

Giving waste a second chance

We partner with local schools and organisations to collect used plastic pens and markers – saving them from landfill and starting their journey toward something better.

Prepped with care

In their workshop, the incredible team at Brothers Make meticulously sort, wash, and chip the plastic into colourful flakes – ready for transformation.

Small batch, big impact

Each pen lid is injection moulded, creating one-of-a-kind pieces. Every lid is then finished by hand – it's small batch production done right.

Love my Wren

I love my wren so much, have ordered 3 more to add to Christmas stockings for my adult children. I did take advantage of the recent discount.💕

A joy!

What a beautiful little pen! I was intrigued by the idea of a refillable pen but didn't want one where I had to buy an obscure refill cartridge for (I have a mug full of those). The Wren ticks every box and in a really beautiful way.
I bought the recycled plastic one and it is a thing of beauty. No blobs, blotches or drips, takes a few seconds to refill, easy to change ink colour and even the tips are replaceable. When capped it is indeed wren-like!
I love it!

Best by far

I've tried other refillable pens but this is the best by far. Others have leaked or needed refilling weekly but the wren is going strong after 2 weeks. I write a lot for my job and this is not only practical but also gorgeous. Definitely would buy again.

I am in Love!

This pen is wonderful, so smooth and easy to write with. If it were slightly longer it would be perfect! It is very well balanced, and overall just stunning. I have already ordered one of the recycled pens so that I'm not carrying this one back and forth from home to work.
