XYPEN Deep Hole Long Nib Markers 24-Pack

XYPEN 20mm Deep Hole Long Nib Waterproof Markers (24-Piece Multi-Color Pack)

Equip your workshop or construction crew with industrial-grade marking precision using the XYPEN Deep Hole Long Nib Marker 24-Pack. Specifically developed for rough carpentry, HVAC installations, metal fabrication, and electrical conduit routing, each marker is fitted with an extended 20 mm slender stainless steel snout that glides through deep mounting holes, bracket slots, and plumbing pass-throughs. This bulk 24-piece utility set supplies six pens each across four essential industrial colors—Jet Black, Crimson Red, Royal Blue, and Forest Green—allowing multiple tradesmen to color-code drilling templates, cut lines, and fastener centers across complex jobsites. Loaded with water-resistant, oil-based permanent ink, each pen lays down crisp, smudge-resistant marks that adhere firmly to dry or oily steel, lumber, concrete blocks, PVC pipes, and glass without fading under heavy jobsite dust or moisture.

Frequently Asked Questions

Are these markers suitable for marking on greasy or oily metal surfaces?

How long do the pens last before running out of ink?
Each marker contains a generous solvent-based ink reservoir sealed by an airtight cap, providing hundreds of linear meters of dense markings.
