Uni-ball UBC63603 Oil-based Paint Marker Blue Emerald

Product Description

The UNI-BALL CORPORATION UBC63603 is an oil-based paint marker designed for permanent marking on a wide range of surfaces, including metal, glass, plastic, wood, rubber, and oily or greasy materials. The medium bullet tip delivers a line width of 1.8 to 2.2mm, producing bold, consistent marks in Blue Emerald. The quick-drying oil-based paint resists water, fading, heat, and abrasion, making it well-suited for harsh job-site conditions. A valve-action ink flow system controls paint delivery and reduces tip dry-out when the marker is left uncapped briefly. The metal barrel contributes to durability and extended marking life on the shop floor or in the field.

This marker is used across manufacturing, construction, automotive service, metal fabrication, and aviation maintenance applications. It marks effectively on both light and dark surfaces, including materials that are difficult to mark with standard ink markers due to surface contamination. Trade professionals in fabrication shops, assembly lines, and field service operations rely on this type of marker for part identification, inspection markings, and layout work. Sold individually per unit.
