The DURA-INK 60 is a permanent ink marker with a durable, medium bullet tip to provide bold, clean marks. Ideal for industrial use, the ergonomic plastic barrel is easy to use even with work gloves. Can be used on metal, cardboard, pipes and tubes, plastic, glass, lumber and timber, polished stone and tile, and more. • Industrial-grade ink dries quickly to leave smear- and water-resistant marks • The strong plastic barrel and clip-cap reduce breakage • Extra-tough tip will not spread or mush, providing longer marking life • Xylene-free formula reduces health concerns • Mark size: 1/8" (3 mm)
