The Brass Wren - Refillable Writing Pen

Beautiful brass, built to last

Brass is one of those materials that just gets better with age – like a good book, or a well-used armchair. It warms to your touch, tells a story with every scuff, and carries the kind of quiet confidence only old souls (and finely tuned pens) can pull off.

The Brass Wren takes all the things people love about the original – refillable, balanced, built to last – and gives it the kind of weight that says: “yep, I mean business." At 53g, it’s more than double the weight of the standard Wren (20g). It’s fitted with a precision Japanese-made tip, engineered to glide across the page, and machined right here in the UK by people who usually make things like luxury watches and aerospace bits. In short: no corner-cutting here.

It’s got that unmistakable feel of a pen that’s going to be with you for the long haul – through ideas, to-dos, doodles, drafts and deep thoughts in cafés. Perfect for modern thinkers with a soft spot for the analogue – the kind who annotate in margins and name their favourite pens.

Built to last, beautifully.

Included in the box:

  • The Brass Wren pen
  • 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 – 53g
  • Made from Brass

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?
Over time the brass will naturally develop its own unique patina. Some love the character this adds, while others prefer to keep their pen polished. Brass requires some extra upkeep to keep it nice and shiny! Please see video on how to do this here.

so darling!!

the cutest little pen!! writes like a dream and is great to toss in a bag and take on adventures. i find it a teeny bit difficult to use sometimes based on the way i hold my pens, but this is just because it's hard for me to push the reservoir half into the plastic half the whole way for a snug fit. definitely not a pen problem though! more a "disability causing me niche issues" problem! :) i wish i could buy a million more of these and give them to everyone because they're just so cute and convenient. reclaiming and reusing materials is one of my favorite pillars of sustainability, so that's the cherry on top of all the reasons i love this little cutie :))

Stunning

This pen is beautiful. I’m pretty much becoming obsessed with Tom’s Studio offerings. I now have 2 Wrens.
I have slight issues with the extra weight of this brass beauty as I’m used to my original Wren and find it slightly harder work with, along with the fact the barrel is smooth and does not have a matte finish makes my grip not so secure. I still love the pen though. I expect I just need to practice more to get used to this brass Wrens unique personality.
