Key Features

Permanent Blue Marking The blue permanent ink is built for marks that need to stay put. Good when you need layout lines, labels, or job notes that should not wipe off easily. Simple 1-Pack You get one Pica permanent marker, which makes this an easy replacement or add-on for the pouch, truck, or shop drawer. Pica Dry Brand Backup If you already trust Pica layout tools, this marker fits right into the same workflow. It is a straightforward marking tool for everyday trade use.

Overview

Pica 520/41 Blue Permanent Marker, 1-Pack is a permanent marker made for jobsite and workshop marking. This is a permanent marker designed for clear, lasting marks on materials and surfaces where pencil or temporary ink is not enough. Model Number: 520/41. For tradespeople and serious DIY users, it fills a simple but important role: make the mark once and keep moving.

The main advantage here is straightforward. Permanent ink matters when layout lines, part labels, or cut references need to hold up through handling, dust, and normal jobsite contact. The blue ink color also helps when you want a mark that stands out from standard graphite or black notes, especially when sorting pieces, labeling work, or separating one step from another in a build process.

Like most useful shop consumables, the value is in reliability and convenience. A single-marker pack makes sense if you need a direct replacement, want one in a pouch, or prefer to keep a dedicated permanent marker at a bench or in a service bag. There is no extra kit bulk to pay for, and no guesswork about what you are getting.

This Pica marker is a good fit for contractors, installers, carpenters, electricians, plumbers, maintenance techs, and general shop users who need quick permanent marking. It is also a smart pickup for anyone already using Pica layout products and wanting another marking option for jobs where a non-permanent mark will not cut it.
