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 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. When the tip eventually dulls, you can find packs of three replacement tips here.

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