Sustainable writing instruments with a professional design. Have you ever thought about the impact of plastic on the environment? How many pens are thrown away every day? We use pens daily. Imagine how many resources you can save by using replacement refills instead of constantly buying new pens. The ballpoint pen refills for the Pilot Rexgrip Begreen and the Pilot B2P are not only environmentally friendly but also give your favorite pen a second life. The medium line width is approximately 0.3 millimeters – perfect for thin and precise lines. The ink does not fade and remains legible for a long time. Additionally, the durable, reliable, and robust ball joint combined with advanced ink ensures an excellent writing experience.
