Biotube Jim Knock

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. The Jim Knock has been a staple for many ballpoint pen lovers over the years. The comfortable rubber grip fits well in the hand, and paired with water-resistant emulsion ink makes for super smooth writing. All barrels carry .7mm ballpoint ink and are available in four earth-inspired colors. Available in .7mm tip sizes Your choice of 4 beautiful barrels: Ocean Blue Green, Earth Blue, Water Clear, and Sunrise Coral; please note the Sunrise Coral comes with Red ink, the other 3 barrels come with Black ink.
