The Pica 521/46 Black Permanent Marker is a job-ready permanent marker built for durable marking, labeling, and general-purpose layout work. This is a permanent marker designed for labeling and marking on a wide range of surfaces. Model number: 521/46. If you need a black marker that writes clearly, dries to a durable mark, and does not punish you for setting it down uncapped during work, this one is built for that kind of use.

What matters here is not just that it is permanent, but how it behaves in real use. The alcohol-based ink is water resistant and abrasion resistant after a short drying phase, so your marks are better suited for environments where moisture, handling, or surface contact would wipe out a lesser marker. That makes it useful for tagging materials, marking cardboard, and handling general shop or site labeling where the mark needs to remain readable.

The 2 mm to 6 mm chisel tip gives this marker more range than a basic fine-point model. You can use the broader face for bold identification marks and the edge for narrower writing when space is tighter. That is a practical advantage if you do not want to carry separate markers for big labels and medium-width note work.

Pica also builds this marker around its Dry-Safe concept, which allows it to be left open for up to 14 days. On the job, that matters more than it sounds on paper. If you are bouncing between cuts, measurements, inventory notes, or material staging, a marker that tolerates being left uncapped is simply less annoying to live with.

From a material and chemical standpoint, the body is plastic with a felt tip, and the ink is alcohol-based. The formula is listed as free from xylene and toluene, which is worth noting for users who care about the makeup of the ink in day-to-day shop use. It is still a permanent marker, but the formula details make it a little more specific than a generic office supply marker.

This marker is a good fit for tradespeople, warehouse use, shop organization, and serious DIY users who need dependable black marking without overcomplicating the job. If your work involves labeling parts, marking cartons, tagging materials, or making visible notes that need to resist water and rubbing, the Pica 521/46 Black Permanent Marker makes sense. It is simple, but it covers the details that actually matter: durable ink, a useful chisel tip, and better open-cap tolerance than most markers in this class.
