Pica Big Ink Smart-Use Marker XL, White is a permanent deep hole marker for trade work where a regular marker tip comes up short. This is a permanent deep hole marker designed for layout and marking on hard-to-reach surfaces and profiles. Model Number: 170/52/SB. If you work around pipe, tile, metal, concrete, lumber, or other jobsite materials, this marker is built to leave a highly visible white line where standard markers usually struggle.

What makes this marker useful is the combination of deep-hole access and everyday permanent marker function. The 2 to 4 millimeter tip gives you enough point control for accurate marks while still laying down a visible line that stands out on darker materials. On the job, that matters when you are marking cut lines on black pipe, dark tile, coated metal, or other surfaces where a normal dark marker disappears.

Pica calls it a smart-use design because it handles two common problems at once: reach and ink life. The long nose helps you mark inside holes, grooves, and narrow channels, while the reversible nib lets you keep using the marker instead of tossing it early. That is a practical feature, not a gimmick. If you burn through markers doing install work, a reversible nib means less waste and fewer replacements in the pouch.

The quiver cap is another small detail that matters more than it sounds. It makes the marker easier to carry and keep close without it rolling around loose in a bag or pocket. For contractors, installers, and shop users, that means quicker access and less time hunting for the marker you just had in your hand a minute ago.

Surface range is a big part of the appeal here. Based on the available product data, the Pica Big Ink Smart-Use Marker XL is intended for most dry surfaces and is compatible with stone, concrete, metal, wood, dry lumber, pvc pipe, glass, wet and dry tile, dry rubber, and cardboard. That broad material range makes it a strong fit for mixed-trade work, especially when you move from rough framing materials to finish surfaces or mechanical installs in the same day.

At 6.22 inches long, this marker has the size to reach where compact markers cannot, but it is still easy to handle one-handed. The XL format is aimed at users who need a little more control and access than a stubby marker can provide. If your work regularly involves marking recessed spots, edge details, or slick dark materials, this is the kind of marker that earns a permanent spot in the tool bag.

Who should buy it? This marker makes the most sense for tile installers, electricians, plumbers, HVAC techs, metal fabricators, carpenters, and general contractors who need visible marks on varied materials. Serious DIY users working on remodeling, shop projects, or mechanical installs will get the same benefit. If you mostly mark clean paper or basic wood in wide-open areas, this is probably more marker than you need. But if you work in the real world where access is tight and surfaces are inconsistent, the Pica Big Ink Smart-Use Marker XL, White is a smart pickup.
