Enjoy a delightfully smooth and vibrant writing experience with the Pilot Acroball. Its richly pigmented ink is specially formulated to be 80% less viscous than ordinary ballpoint ink. This allows the ball in the pen tip to rotate smoothly, providing an effortless, skip-free writing experience. This T series Acroball pen combines the fantastic performance of the classic Acroball with an eye-catching assortment of metallic and pearlescent body colors. It features a comfortable, non-slip rubber grip section with a tire tread-like texture. It is made with recycled plastic, making it environmentally friendly too!
