The Pica 170/41/SB Blue Ink Marker For Deep Hole w/ Quiver Holder, 1-Pack is a permanent deep hole marker built for trade work where a regular marker cannot reach cleanly or consistently. This is a permanent deep hole marker designed for layout and marking on dry jobsite materials. Model Number: 170/41/SB. If you need one marker that can handle both normal surface marking and tighter access points, this is the point of this tool.

What separates this marker from a basic permanent marker is the tip design. The 2 to 4 millimeter reversible nib gives you a combination of visibility and control, so you can make marks that are easy to see without giving up accuracy. On the job, that means cleaner reference lines on metal, wood, concrete, stone, cardboard, glass, tile, rubber, and pvc pipe across a wide range of dry surfaces.

Pica calls it a smart-use marker because it covers two common needs with one tool: standard marking and deep access marking. That matters if you are laying out cuts, marking pipe runs, or working around channels and recesses where a short marker body or broad tip gets in the way. The reversible nib is also a practical design choice because it helps you use more of the marker before replacing it.

Jobsite carry is another strong point here. The quiver cap keeps the marker clipped and protected, which sounds minor until you spend a day climbing ladders, moving material, or shifting between layout tasks. A marker that stays in your pocket and stays ready is the one you actually use, and this one is built around that idea.

For real-world use, the blue ink stands out well on many common work surfaces, especially when you need a visible line on wood, metal, or light-colored plastic pipe. This is not a specialty office marker. It is a layout and marking tool for tradespeople who need quick, readable marks that hold on dry materials.

The Pica 170/41/SB Blue Ink Marker For Deep Hole w/ Quiver Holder, 1-Pack makes the most sense for contractors, installers, remodelers, carpenters, metalworkers, and serious DIY users who are tired of forcing the wrong marker into the wrong job. If your work involves repeated measuring, fit-up, cut marking, or transfer marks in tight spots, this is the kind of tool that earns its place fast.
