Inspired by the humble blueberry (an unsung hero of fruity perfection), our Blueberry Special Edition features a juicy ombré effect. Flowing from deep berry blue to soft sky tones, the hand dip-dyed finish means every pen is completely unique.

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 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!

Looking for a waterproof option? We’d suggest our No.60 Pigment Black, Sailor Kiwa-guro or Platinum Carbon inks - we’ve tested both, and they flow beautifully.

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.
