The Frixion Ball 2 Biz features a rotating mechanism to switch between red and black ink in a matte black metal body that suits any business setting. The sleek metal is smooth to the touch and slides effortlessly through the pen holder of the planner cover, while the pen tip writes in a slim 0.2 mm line for detailed writing anywhere in the pages. The eraser is concealed with a cap that perfectly matches the pen body to give the pen one of the more polished appearances among the Frixion lineup.
