A clever clip-on companion for your Field Mouse – made from 100% recycled plastic by our friends at Brothers Make.

This lightweight carabiner has been designed to keep your Field Mouse pen (and your keys) close at hand – perfect for clipping to your bag, belt, or sketchbook. It’s made in the UK from recycled plastic in our Write Off colours, giving pen waste a second life in spirit if not in substance.

Strong, ergonomic, and full of character, it’s a little nod to everyday creativity – helping you stay ready for those spontaneous scribbles and flashes of inspiration, wherever they strike.
