The Field Mouse is a tiny, go-anywhere writing companion for the moments an idea strikes away from your desk. Small enough to clip onto your keys, a lanyard, or the strap of a bag, it stays close for quick notes, little sketches, and the thoughts you don’t want to lose between here and home.
Fitted with a Japanese-made writing tip, it refills with standard fountain pen ink, so it’s a pen you keep rather than one you throw away. We carry it in two all-metal finishes: warm solid brass that picks up character the more you carry it, and cool, quietly polished stainless steel. Spare reservoirs and replacement tips are available as options, too.
