The Pica 590/36 Green Marker, 12-Pack is a lumber and industrial marking crayon from Pica Dry. This is a marking crayon designed for marking lumber and industrial materials. Model Number: 590/36. If you need a simple, highly visible marking tool for rough surfaces where a standard pencil is not the right fit, this is the kind of product that earns its place fast.

Pica positions this marker in its Classic line, and the product data on the packaging makes the use case clear: lumber and industrial marking. That matters because not every marker is made for rough, dirty, or uneven stock. On framing lumber, timber, or shop material that does not take a clean pencil line well, a purpose-built crayon gives you a more obvious reference mark without overcomplicating the job.

The size is part of the appeal here. Each crayon measures 12 mm across and 120 mm long, so you get a larger format than a standard pencil. In real use, that means easier handling with work gloves, quicker grab-and-go use on site, and better visibility in a pocket, pouch, or gang box. The green color also helps when you need marks that stand out from the material underneath.

This Pica marker is a practical fit for tradespeople who mark cut lines, sort stock, identify workpieces, or flag material during layout and prep. Carpenters, woodworkers, yard crews, and general contractors will all understand where this type of marker fits in the workflow. It is not trying to be a fine drafting tool. It is built for clear, fast jobsite marking where durability and visibility matter more than precision-line cosmetics.

The 12-pack format is another reason this product makes sense for professional use. Consumables disappear, get borrowed, or end up spread across different kits. Having a dozen on hand keeps crews moving and reduces downtime hunting for a marker when layout work starts.

If your work regularly involves rough lumber, timber, or industrial material handling, the Pica 590/36 Green Marker, 12-Pack is a straightforward solution. It is best for users who want a dedicated industrial marking crayon from a known marking-tool brand rather than making do with whatever pencil happens to be nearby.
