Bsc Preferred MK401BK Permanent Markers Case of 12

Product Description

The BSC PREFERRED MK401BK is an industrial-grade permanent marker designed for heavy-duty marking tasks. Built with a sturdy felt tip, it delivers water-resistant, permanent ink that dries quickly on contact. This marker is formulated to write on wet and oily surfaces where standard markers fail, making it a reliable tool for job site tagging, parts labeling, and material identification. Sold as a case of 12, it suits high-volume environments where markers see frequent use and regular replacement. Contractors, technicians, and warehouse personnel working in demanding conditions will find these markers hold up through routine daily use.

The MK401BK is suited for industrial and commercial environments including HVAC shops, plumbing supply areas, electrical job sites, and warehouse operations. The ability to mark on oily metal, damp pipe, and wet surfaces makes it practical for field service and mechanical work where surfaces are rarely clean and dry. A case quantity of 12 supports team supply needs without frequent reorder interruptions.
