Circular Ballpoint Pen · Natural

An everyday pen, made with care

This minimalist ballpoint pen is made in Germany from starch-based bioplastic blended with elephant grass. Light in the hand and simple in form, it’s designed for everyday writing — notes, lists, and quiet moments at your desk.

Handmade using 3D printing and crafted entirely from European materials, the pen is climate-neutral, fully recyclable, and created with circularity at its heart. When it reaches the end of its life, it can be returned to us free of charge and remade into something new.

A small object, thoughtfully designed to be used well.
