The Pica 150/41/SB Blue Ink Marker For Deep Hole w/ Quiver Holder, 1-Pack is a specialty deep-hole marker built for layout work in places a regular marker cannot reach. This is a permanent marker designed for marking dry surfaces and hard-to-reach layout points. Model Number: 150/41/SB. If you spend time marking inside drilled holes, brackets, electrical boxes, cabinet hardware locations, or tight framing pockets, this is the kind of simple tool that saves time fast.

What matters here is the extended stainless steel tip. Instead of trying to jam a fat-bodied marker into a narrow opening and hoping the mark lands where you need it, this marker is made specifically for deep access. The 1.5 mm bullet tip gives you a visible mark without turning fine layout into a blurry mess, and the permanent blue ink stands out well on many common dry jobsite materials.

The design is practical, not gimmicky. The quiver holder gives you a place to keep the marker secure and easy to grab with one hand, which is exactly what you want when you are on a ladder, leaning into a cabinet, or moving through repetitive install work. For tradespeople who mark constantly throughout the day, that holder is not just a convenience feature. It keeps the marker accessible and reduces the chance of misplacing it.

The Pica 150/41/SB Blue Ink Marker For Deep Hole w/ Quiver Holder, 1-Pack is also made for real material contact. The extended nib is stainless steel, which helps it hold up better when you are reaching into rough openings or making contact around metal edges and drilled passages. According to the source data, it marks on almost all kinds of dry surfaces, and the ink is permanent while still being removable from glossy surfaces with alcohol or other suitable solvents.

This is not a general desk marker pretending to be a jobsite tool. It is a purpose-built layout marker for installers, electricians, carpenters, cabinet crews, HVAC techs, and anyone else who needs accurate marks in spots that are awkward to reach. If your work involves repeat drilling, hardware placement, cutout transfer, or anchor point marking, this tool makes those small but important steps easier and more consistent.
