The Brass Wren - Refillable Writing Pen

Beautiful brass, built to last

CHF 72.00

Adding to Cart Added to Cart

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.

  • The Brass Wren pen
  • Japanese-made Writing Tip*

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.
