Industrial marking tool

The uni-ball 63603 is an oil-based paint marker built for industrial environments where permanent, opaque marks are required on metal, plastic, glass and other difficult surfaces. It suits maintenance crews, fabricators and technicians who need reliable identification on oily, greasy or dark substrates.

Valve-action flow control

A valve mechanism regulates ink delivery and prevents the tip from drying out when the marker is left uncapped during shift work. The medium bullet tip produces consistent line width on rough or smooth surfaces, while the white metal barrel resists solvent exposure and rough handling on site.

Replaces standard felt-tip markers

Conventional markers fail on contaminated or low-energy surfaces; this paint marker adheres where they bead or wipe away. The upgrade is justified when marks must survive weather, abrasion, heat or chemical wash-down without fading or lifting.
