Introducing an eco-friendly ballpoint pen with eco-friendly refills! Zebra has created the Biotube, the pen industry’s first ballpoint pen series using biomass plastic derived from sugarcane. Biomass plastic is a plastic that uses renewable organic resources such as plants and raw materials. This one-of-a-kind series is designed to be wholly environmentally friendly, including the pen body, refill, and refill packaging. These efforts reduce CO2 emissions by 73% compared to conventional products! We love to see Zebra innovating and hopefully this leads the pen world to a higher industry standard.
