This marker is designed for both everyday writing and marking in hard-to-reach areas. It writes smoothly on nearly all surfaces, including metal, stone, glass, wood, plastic, and leather. The extra-long, narrow 30 mm nib is ideal for drill holes, tight corners, shelf installations, and assembly work. The 0.7 mm round tip delivers precise fine lines. Equipped with a practical holster, the marker can be securely clipped to workwear or tool belts and quickly drawn for efficient one-hand operation. Quick-drying ink is waterproof and smudge-resistant, ensuring clear, reliable marks even in demanding environments.
