The rOtring 600 is an elegant metal ballpoint pen designed with precision and comfort in mind. It features the rOtring brass mechanism for precise lead advancement and a fixed lead guide sleeve that prevents breakage while allowing an unobstructed view of the page for accurate drawing with a ruler. The hexagonal barrel ensures fatigue-free writing and drawing, preventing the pen from slipping when placed on surfaces. The non-slip, knurled metal grip ensures that the pen sits securely in your hand and does not accidentally slip out. Under the push-button cap, there is an integrated eraser that allows for quick corrections, ensuring that mistakes are not permanent.
