The Pica Dry Deep Hole Marker Set is a three-piece marking set built for reaching into narrow, hard-to-access spots where regular markers come up short. This is a deep hole marker set designed for marking in tight spaces and on almost all kinds of dry surfaces. Model number 150/40-46-41. If you do install work, layout, or fit-up where the mark needs to land inside a drilled opening or behind an obstruction, this set solves a very real problem.

What makes this set useful is the extended tip. Pica pairs permanent alcohol-based ink with a stainless steel telescopic tip so the marker can get farther into holes and recesses than a stubby body marker. In practical terms, that means cleaner transfer marks in places where a carpenter pencil, paint marker, or standard felt tip simply cannot reach. You spend less time estimating and less time pulling things apart because the mark landed in the wrong spot.

The ink is made for jobsite conditions, not just shop benches. It marks on almost all kinds of dry surfaces and becomes instantly water and abrasion resistant. That gives you a mark that stays visible through handling, carrying, and light contact while you keep moving through the task. On glossy surfaces, the ink can be removed with alcohol and other usable solvents, which is useful when you need a temporary mark without switching tools.

Pica also built some smart life into the tip itself. The fiber nib can be twisted several times by 180 degrees for additional service life, and the design uses the full 7 mm of the nib's abrasion length instead of just 2 mm. Pica states that this can deliver up to 3 times more marking capacity. That is the kind of detail that matters on consumable tools because it stretches usefulness before you need to replace anything.

From a handling standpoint, the quiver cap is not just packaging. It uses a reinforced clip for strong, permanent fixation on a trouser pocket and is designed for one-handed use. That matters when you are carrying material, balancing on a ladder, or bouncing between measurements and marks. The set includes red, black, and blue marker bodies, which gives you simple color choice for different tasks, crews, or material callouts.

If you routinely mark through hardware openings, in drilled holes, behind brackets, inside cabinets, or anywhere clearance is limited, this marker set earns its keep quickly. It is a strong fit for contractors, installers, maintenance techs, and serious DIY users who are tired of forcing the wrong marker into precision work. This is not a generic marker pack. It is a purpose-built deep hole marking set for real access problems.
