About this item

Every builder, electrician, and DIY enthusiast knows the frustration—you need to mark a drill point inside a tight mounting hole, but your marker is too short to reach. Or worse, you mark it from the outside, and the hole ends up off by millimeters, ruining the entire piece. This is exactly why the Long Nib Marker Pen was created. With its extra-long 20mm nib and slim 129mm total length, it reaches into deep holes, narrow pipes, and tight corners that ordinary markers simply can't access. The quick-dry, waterproof ink writes clearly on metal, wood, tile, glass, and more—so your marks stay visible, precise, and permanent through drilling, cutting, and installation. Whether you're on a construction site, in a workshop, or tackling a home DIY project, this marker is the small tool that makes a big difference.Specifications- Marker Length: 129mm total- Nib Length: 20mm extended nib- Ink Type: Quick-dry, waterproof, fade-resistant- Surfaces: Metal, aluminum, concrete, tile, glass, wood, plastic, and other dry, dust-free surfaces- Applications: Deep hole marking, drilling guides, carpenter marking, construction layout, industrial labeling, pipe marking, electrical work- Design: Pen clip for pocket attachment, compact, portableWhat's Included- 10 x Long Nib Marker PensWhy You'll Love ItReaches What Other Markers Can'tThere's nothing more frustrating than trying to mark a drill hole deep inside a pipe or through a mounting bracket, only to find your marker is too short to reach. This marker's 20mm long nib extends into the tightest spots—passing through small mounting holes, reaching inside electrical panels, and accessing narrow gaps. You can mark the exact spot directly, eliminating the guesswork and errors that happen when you try to mark from the outside. The result? Perfectly aligned holes and professionally accurate work, every time.Marks That Survive the JobConstruction and workshop environments are tough on tools, and ink is no exception. This marker uses a specially formulated ink that dries in seconds and becomes water-resistant once dry. Rain, humidity, or accidental wet hands won't smudge or wash away your marks. It's designed for South African conditions—from humid coastal areas to dusty construction sites—keeping your lines clear and visible until you're ready to cut, drill, or install.Works on Nearly Every SurfaceOne marker, countless materials. The fine round tip glides smoothly across metal, concrete, tile, glass, wood, plastic, and aluminum. Need to mark a tile before drilling? Done. Writing a note on a PVC pipe? Easy. Laying out a cut line on wood or metal? No problem. This versatility means you can keep one marker in your toolbox and use it for almost every job, from electrical work to furniture assembly.Built for Daily Use on SiteThe high-quality polypropylene body is tough enough to survive the inevitable drops and knocks of a busy worksite. The nib is reinforced and break-resistant, maintaining its shape through repeated use on rough surfaces. And the cap seals tightly to prevent the ink from drying out between jobs. It's a marker that keeps working as hard as you do—day in, day out.Pocket-Ready, Always Within ReachThe pen clip is a small detail that makes a huge difference on site. Clip it to your shirt pocket, tool belt, or apron—it's always right there when you need it. No more searching through toolboxes or walking back to the workbench for a marker. It's the kind of convenience that saves seconds on every task, and seconds add up to hours over the course of a project.Usage & Care Tips- Surface Preparation – For best results, mark on clean, dry, dust-free surfaces. Remove oil, grease, or dirt before marking to ensure proper ink adhesion. Allow the ink to dry for a few seconds before handling the marked surface.- Storage – Always cap the marker immediately after use to prevent the nib from drying out. Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep the markers horizontal or upright with the nib pointing down for optimal ink flow.- Nib Care – If the nib becomes dry or hard, try dipping the tip in a small amount of rubbing alcohol and gently wiping it clean. Avoid pressing too hard on the nib to preserve its shape and longevity. The reinforced tip is durable but should be treated with reasonable care.- Ink Characteristics – The ink is quick-drying and water-resistant once fully dry. It may not be fully waterproof immediately after application—allow 10-20 seconds for the ink to set before exposing to moisture.- Surface Testing – Although this marker works on a wide range of surfaces, we recommend testing on an inconspicuous area first, especially on delicate finishes or porous materials, to ensure compatibility.Note- Deep Hole Marking – The 20mm nib and slim design are specifically engineered for marking through small mounting holes, pipe interiors, and other hard-to-reach areas. This allows for precise marking directly on the fixing surface, eliminating alignment errors.- Drying Time – The ink is designed to dry quickly on most surfaces, typically within seconds. However, drying time may vary depending on the material and humidity level.- Surface Suitability – While versatile, this marker works best on dry, clean surfaces. Very rough or textured surfaces may affect the clarity of the mark.- Ink Durability – The ink is water-resistant and fade-resistant once dry, making it suitable for long-term marking and outdoor use.- Portability – Designed with a practical pen clip, it attaches easily to pockets, tool belts, or aprons for quick access on the job.- Longevity – Each marker delivers consistent, skip-free lines for a reliable marking experience. Proper capping and storage will extend the life of each marker.- Not for Food Contact – This marker is not designed for writing on food-contact surfaces, kitchenware, or items that will be consumed. For industrial, workshop, and construction use only.
