The Pica Dry 150/46 Marker for Deep Holes, Black is a permanent deep hole marker built for tradespeople who need to mark through narrow openings and onto hard-to-reach surfaces. This is a marking tool designed for layout work on dry jobsite materials. Model Number: 150/46. If you work around framing, rough-in, cabinetry, metal, tile, pipe, or general install work, this marker solves a very real problem: getting a clean, visible mark where a standard marker body is too thick to fit.

What makes this marker different is the extended stainless steel tip. Instead of stopping at the edge of a drilled hole, bracket opening, or hardware recess, the tip reaches in so you can transfer marks accurately without awkward guessing. That saves time when you're laying out anchor points, marking cut locations, or tracing hidden fastener positions. The 1.5 mm tip size gives you a visible line without getting overly sloppy.

The ink is permanent and alcohol-based, and it is designed to mark on almost all kinds of dry surfaces. It is also instantly water and abrasion resistant, which is a big deal when your mark needs to survive handling, dust, and material movement before the cut or install happens. On glossy surfaces, the ink can be removed with alcohol or other suitable solvents, so you get permanence where you want it and cleanup options where you need them.

Pica also put some thought into the way this marker lives on the job. The quiver cap with clip is there for a reason. It gives you secure pocket carry and faster one-handed access, which sounds small until you've used a marker all day climbing ladders, moving materials, or bouncing between tools. The cap is meant to stay put so the marker is ready when you are.

One of the smartest details here is the reversible nib design. The fiber nib can be turned 180 degrees to get more life from the marker, and the telescopic tip is designed to use more of the nib length than a typical deep hole marker. In practical terms, that means more usable ink and longer service before replacement. It is a simple idea, but on a consumable tool like this, getting extra life out of every marker matters.

The Pica Dry 150/46 Marker for Deep Holes, Black is a good fit for contractors, remodelers, carpenters, electricians, plumbers, HVAC installers, and serious DIY users who work across mixed materials. It is especially useful when marking wood, metal, concrete, stone, PVC pipe, glass, cardboard, dry rubber, and tile in spots your regular marker cannot reach cleanly. If your work involves transfer marks inside holes or around installed components, this is the kind of marker that earns its place fast.
