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

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 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!
