Wren - Take Flight & Write

A beautiful and infinitely refillable writing pen, equipped with a Japanese-made writing tip.

Every year, millions of disposable pens are thrown-away, adding to the growing environmental waste. Similar to printer ink cartridges, pen companies design their products for short-term use, pushing you to repeatedly buy new pens or refills. It's profitable for them, but disastrous for the planet – and limits your creative freedom.

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

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.

Great little pen for everyday writing....I can leave the lid off for longer without worrying it will dry out too

Little pen

I was eyeing the Lumos for a long time, but I would only use it to write with. That made the price a but too high for the usage of the pen. Eventually, I almost ordered a Lumos, but then I got an e-mail about the Wren. So happy that I've waited for this one to come out. I'm lefthanded, so smudging out ink is really a problem. With this pen and tip, the ink dries so fast, no smudging at all. The pen feels very good too write with. Perfect weight en perfect to hold. I get no cramps in my fingers/wrist when writing with the Wren. What I've been searching for for so many years is al packed in this little one. I love it! I'm also a sucker for personalised items, so that you can choose the color of the cap and the body was a plus aswell!

I LOVE this pen!

I have the Lumos, Studio Fountain pen, and Studio Pocket Fountain pen. Like those, the craftsmanship and quality are superb, and I love writing with refillable felt tips. I would love to see this same thing in a standard-sized pen. It would be a hit!

Great pen, with a little critique

I have been using the Lumos now for half a year and the Wren has completed my writing tools kit. It provides with a great writing experience and I am considering it as a gift for important people in my life. Only critique: the two o-rings are really keeping the Wren nicely closed, and this is a good. But it is hard to open and I wonder if replacement rings will be available at a certain point. Using o-rings continuously for my work, I know how fast they degrade and since they are already stiff now, I suggest to consider providing them.

Phenomenal pen, with a couple small caveats

As a felt/fiber pen lover who also loves writing in brown ink, finding a pen that would let me write in the color I wished was virtually impossible, outside of specialty artists' fine liners. I'm no artist or pen guru, but I fell in love with the Wren as soon as I saw it. It fills easily and writes beautifully on Tomoe River Paper, Midori Paper, and even just regular copy paper and post-it notes. This is truly a workhorse pen, and I'm grateful for it. I look forward to using it every day.

I have a couple SMALL critiques, namely that this needs a clip. If this is to be a pen I can carry around, having a clip would be incredibly helpful. I'd be able to clip it to the inside of my purse so I don't have to fish around the bottom for it, to the inside of a pocket, or to a Moleskine notebook. I'm on the hunt for a clip that will it, but it'd be great if future iterations had one, or the option for one.

Secondly, and this isn't even really a critique, but I'd love to see this as a normal-size pen that can take a larger cartridge (AND HAS A CLIP) so you can use it longer between refills. I write a lot both personally and for work, so having one that doesn't have to be refilled as often, but has that DANK felt tip, would make my life.

Nevertheless, this is a great pen! My absolute favorite already. This is true innovation, and I hope more pen creators follow suit. :)
