PICA 4043 Dry White Refill Leads, 10-Pack is a refill lead set for the Pica Dry Automatic pencil, Model Number 4043. This is a mechanical pencil refill designed for jobsite marking on wet, glossy, rough, oily, and dry surfaces. If you already use a Pica Dry marker and need a white line that stays visible on dark material, tile, stone, metal, or finished surfaces, this is the refill that makes that tool worth carrying.

What makes these leads useful is not just the color. White marks show up clearly on dark surfaces like slate, tile, rubber, metal, and stained wood where standard graphite disappears. The leads are described as water-jet resistant and permanent, which matters when layout lines need to stay put through handling, moisture, or wet cutting conditions. That is especially relevant for tile work and stone work where a mark can vanish fast once water gets involved.

The 2.8 mm tip size gives you a thicker, easier-to-see line than a standard pencil, but it still works for controlled layout. These leads come pre-sharpened, so you are not wasting time getting started. For trades that do a lot of repeated measuring, fitting, and trimming, that small detail saves hassle through the day.

Pica also calls out the low-chloride formula, which is important if you mark on stainless steel. That makes these refill leads a better fit for more demanding shop and install work than a generic marking stick or carpenter pencil. When a spec matters, this is one of them. If you work around stainless, you want the right marking material, not whatever happens to be in the pouch.

In real use, the big advantage is surface range. Source data lists stone, concrete, metal, wood, pvc pipe, glass, wet and dry tile, wet and dry rubber, and cardboard. That means one refill type can cover punch-list work, flooring layout, tile fitting, fabrication prep, and general construction marking without switching between different pencils or crayons.

Compatibility is straightforward. These refill leads are made for the Pica Dry Automatic pencil and are listed for use with PA3030/SB. If you already run that Pica Dry system, these are the correct white replacement leads to keep on hand. They are a refill accessory, not a standalone marker.

Who should buy them? Tile setters, remodelers, flooring installers, general contractors, metalworkers, and serious DIY users who need visible marks on tricky materials. If most of your marking happens on clean lumber only, standard leads may be enough. If you work on dark, wet, glossy, or mixed materials, these white Pica Dry refill leads make a lot more sense.
