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.

Not just good pens

So I purchased my wren after buying the lumos pro single. The wren arrived and the tips wouldn't stay. I contacted the team at toms studio last night. They identified my problem and have organised a replacement to a 'faulty' part by lunchtime today. The customer service interaction was polite and genuinely seemed interested in ensuring my happiness with my purchase. Well it's worked im a customer for life. Although with the quality of the pens not sure how many pens I'll need going forward.

Pen Perfection

A.few weeks ago, I received my 1st Wren in the mail. I took it to work the next day and loved using it so much, I ordered a second one that same day. I am anxiously awaiting my 2nd one's arrival (Raspberry/Blush) & will be inking it with a matching color ink. The writing tips are smooth and precise. I find joy in small things, so the small but mighty Wren gives me daily joy!

Beautiful workmanship and a lovely weighted pen, smooth writing and no smudging, and being small is easy to carry around.

Wonderful pen!

I really value things that are carefully and lovingly made, using great materials and built to last. My Wren and Lumos are just that. It’s like using art to create art. The pens are gorgeous, and are so functional and fun to use. Everything is very well thought out. Thanks Tom, keep the great ideas coming!
