Expo Thick Black Dry Erase Marker — Single Black Marker for Bold Whiteboard Writing

Make every idea stand out with the Expo Dry Erase Markers Thick Single Black. This dedicated black marker is built for high-visibility writing on whiteboard surfaces, so your notes, diagrams, and presentations pop from across the room. Ideal when you want a single, reliable marker that delivers crisp, broad lines without clutter.

Bold, broad lines for maximum visibility

The thick tip delivers substantial, legible strokes ideal for headlines, emphasis, and large diagrams. It’s perfect for classroom lessons, training sessions, or team meetings where clear communication matters and quick comprehension is essential.

Smooth writing, quick-drying, easily erases

Ink flows smoothly onto non-porous whiteboards and dries rapidly to minimize smudging during note-taking. When you’re ready to reset, the marks erase cleanly with a standard whiteboard eraser or cloth, leaving the surface ready for the next idea.

Reliable performance you can count on

Expo markers are designed for consistent ink flow and bold black pigment that remains highly legible in varied lighting. The single black marker format is convenient for individuals who prefer a dedicated color or are stocking up for a shared workspace without committing to a multi-pack.

Ideal use cases

• Classrooms and lecture halls for clear, visible instructions and diagrams
• Presentations and trainings where large, readable text is essential
• Home offices and study spaces for planning, brainstorming, and project planning
• Temporary signage or labeling on whiteboards during workshops and events

Pro tips for best results

Shake gently before initial use to prime the tip, then press lightly to begin a smooth, continuous line. Recap tightly after each use to preserve ink and tip integrity. For long sessions, keep the marker capped when not in use and store on a clean, dry surface away from extreme heat.
