Eddings Black 141F boasts bold and vibrant lines from its fine tip. Fast drying ink and rounded barrel mean this pen is suitable for both right and left handers. Fine 0.6mm nib is both strong and delicate at crafting a fine and even line. Writes permanently on almost all non-porous surfaces including wood, glass, plastic and ceramic. Superb waterproof ink ensures your markings will remain permanent and fade resistant over time.
