XYPEN Deep Hole Long Nib Markers 6-Pack

XYPEN 30mm Deep Hole Long Nib Waterproof Markers (6-Piece Multi-Color Pack)

Reach deep into screw recesses, pre-drilled brackets, pipe channels, and narrow electrical junction boxes with the XYPEN Deep Hole Long Nib Marker Set. Engineered for carpenters, plumbers, electricians, and metal fabricators, each marker features an extended 30 mm slender stainless steel snout that glides effortlessly through deep drill holes where standard bulky pens cannot reach. This practical 6-piece utility pack contains two markers each in high-contrast Jet Black, Crimson Red, and Industrial Blue. Powered by fast-drying, oil-based permanent ink, the formulation bonds instantly to dry or oily steel, rough lumber, masonry, PVC conduit, and glass, leaving smear-resistant reference marks that withstand construction site dust, water splashes, and handling abrasion.

Frequently Asked Questions

Can these markers write on wet or dusty timber?
Yes, the specialized permanent oil-based ink cuts through fine dust and dampness, anchoring firmly to rough construction surfaces.

Will the 30 mm metal snout bend under heavy hand pressure?
No, the snout is crafted from hardened stainless steel tubing that resists bending and prevents fiber tip deformation when traced along metal brackets.

How do I remove the marks if needed?
On non-porous surfaces like aluminum, PVC, or glass, marks can be removed using isopropyl alcohol or acetone.
