uni-ball 63606 Violet Medium Bullet Marker

Industrial marker for permanent identification

This uni-ball Uni-Paint PX-20 marker delivers opaque violet ink on virtually any surface. The oil-based formula creates permanent marks that resist water, fading, heat and abrasion. It is built for manufacturing, construction, automotive and aviation environments where durable identification is required. Valve action controls ink flow and prevents the tip from drying out when left uncapped.

Oil-based ink limits on certain substrates

The permanent paint formula adheres to oily, greasy and glossy surfaces where conventional markers fail. Quick-drying properties reduce smudging during handling. However, the medium bullet tip width restricts fine detail work on small components. Users needing microscopic legibility or solvent-removable marks should consider alternative marking methods.

Metal barrel and valve action for site durability

A metal barrel protects the ink reservoir from impact on job sites. The valve action mechanism maintains consistent flow after storage and prevents dry-out without a cap. The medium bullet tip withstands abrasion on rough materials such as concrete and metal fabrications. White barrel colour allows quick visual identification of the violet ink inside.
