Pica 524/41 Blue Paint Marker is a permanent paint marker built for clear marking on jobsite materials and shop surfaces. This is a paint marker designed for labeling, layout marking, and identifying parts on materials like metal, cardboard, glass, and similar surfaces. Model Number: A14721410P52441. If you need a mark that is easier to see and more durable than a basic felt-tip marker line, this is the kind of marker you keep in the truck, gang box, or drawer at the bench.

The big selling point here is simple: it puts down blue paint, not just dye. That matters when you are marking material that is dusty, dark, smooth, or slightly oily, where ordinary marker ink can look weak. The listed 2 to 4 millimeter line size gives you a useful middle ground. It is fine enough for labeling and part identification, but bold enough to stay visible when the surface is less than perfect.

Pica positions the Classic 524 as a paint marker for industrial and trade use, and the format reflects that. It is a straightforward marker pen with an oil-based paint ink and a round tip. That combination is a practical fit for maintenance crews, metal shops, installers, fabricators, and general contractors who need quick visual marking without dragging out a soapstone holder, lumber crayon, or specialty marker for every task.

Water resistance is one of the key details worth paying attention to. The source data lists this marker as waterproof, which is important when the mark needs to survive handling, storage, or exposure to damp conditions. For packaging labels, identifying cut parts, or marking components before installation, that kind of durability saves time because you are not remarking the same material later.

In day-to-day use, this blue paint marker makes the most sense for anyone who needs fast, readable marks across mixed materials. It is especially useful when you want a color-specific mark for sorting, staging, or process control. One pack means you are getting a single marker, so this is a good fit if you are replacing an existing one, adding a specific color to your kit, or stocking a bench with purpose-specific markers instead of a generic multipack.

If your work involves material handling, metal marking, packaging, shop organization, or general layout work, this marker earns its keep by being simple and dependable. It is not a multi-tool or a gimmick item. It is a dedicated industrial paint marker that does one job well: making visible, lasting marks where a regular pen or marker falls short.
