5 PCS Long Nib Marker Pens 20mm

5-Pack Deep Hole Marker Pens

This set contains five construction markers each fitted with a 20mm long nib. The colour-coded barrels match the ink inside for quick identification on busy job sites. They are designed for tradespeople who need to mark through narrow openings or deep recesses. The waterproof ink adheres to metal, steel, tile, glass and wood.

Upgrade From Standard Short-Nib Pens

Conventional carpenter pencils or stubby markers cannot reach into drilled holes, tight corners or narrow channels. These long-nib pens eliminate the need to guess or estimate mark placement in deep cavities. The switch is worthwhile whenever layout work involves through-holes, pipe penetrations or recessed hardware locations. Quick-dry ink also reduces smudging on slick surfaces.

Suited For Wet Or Dusty Site Marking

Carpenters, plumbers, electricians and tile setters benefit from the waterproof formula that survives damp lumber and wet saw spray. The five-colour pack covers colour-coding needs for different trades or cut types. Workers who only mark flat, dry lumber in clean conditions may find a simple pencil faster and cheaper. Anyone needing ultra-fine lines for precision joinery should look at dedicated layout knives instead.
