Sharpie 30003B Fine Point Permanent Marker Blue

Product Description

The SHARPIE 30003B is a fine point permanent marker with solvent-based ink designed for marking on a wide range of surfaces encountered in trade and industrial work. The fine point tip delivers precise, legible lines on metal, PVC, conduit, pipe, duct board, and other materials common to HVAC, plumbing, and electrical jobsites. Solvent-based ink bonds quickly and resists smearing, moisture, and fading, making marks that hold up on both porous and non-porous surfaces. This is a single-unit marker sold individually, suited for technicians who need a reliable marking tool on the truck or in the shop.

The 30003B is well suited for professionals who need to mark pipe sizing, circuit identifications, equipment tags, or service notations directly on components and materials. Its fine point tip keeps markings compact and readable in tight spaces, such as labeling conduit runs, scribing cut lines on duct, or noting refrigerant circuit points on equipment. The blue ink color offers clear contrast on light-colored surfaces including white PVC and galvanized sheet metal.
