The pen for when you don’t have a pen.


Say hello to The Field Mouse – your go-everywhere, write-anywhere infinitely refillable sidekick. Inspired by its folklore namesake, this tiny tool is made for moments when ideas strike and your usual pen is miles away. Hook it to your keys, your lanyard, or your bag, and you’ll never be caught scribble-less again.

We love it paired with our handmade Leather Key Fob – a beautiful blend of materials and craftsmanship.

  • Pocket-sized, lightweight and ready for spur-of-the-moment notes or quick sketches
  • Fitted with a writing tip and refillable with any standard fountain pen ink
  • Built from solid brass or stainless steel for ultimate everyday toughness

  • The Field Mouse 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 – 63mm
  • Length uncapped – 54mm
  • Weight: Brass – 23g / Stainless Steel – 21g
  • Made from Brass or Stainless Steel

Full FAQs and a video guide to getting started with your Field Mouse can be found here.

What ink can I use?
The Field Mouse is compatible with all standard Fountain Pen Inks and we have a beautiful range of colours here. Please note the Field Mouse 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. When the tip eventually dulls, you can find packs of three replacement tips here.

Anything else I should know?
Brass requires some extra upkeep if you'd like to keep it nice and shiny! Please see video on how to do this here.
