Circular Ballpoint Pen made from recycled PET-G

Sustainable Writing Redefined: The Circular Ballpoint Pen

Are you looking for a pen that supports the circular economy with every use? The Circular Ballpoint Pen from Prototo is a durable companion made from recycled PET-G – a material derived from industrial waste like packaging and beverage bottles. Minimalist design meets maximum environmental responsibility.

Material & Manufacturing

The ballpoint pen is handcrafted in Germany using an innovative 3D printing process from recycled PET-G. The casing has a matte, tactile, and durable surface – ideal for long-lasting writing comfort. The pen contains a high-quality metal refill (document-proof according to ISO 12757-2) and a piano wire spring mechanism, both made in Germany. The packaging is made from recycled paper from Switzerland. The special feature: You can return your used pen free of charge so that Prototo can make new products from it.

Who is this for?

The Circular Ballpoint Pen is perfect for you if recycling and climate protection are important to you when writing. Whether you value minimalist design, work professionally or creatively, or are looking for sustainable gift ideas – this pen is a practical companion for your everyday life. With every stroke, you support a true circular economy.
