Marker Bonus Velleda Liquid Tank black P12 — refillable liquid ink whiteboard marker

Refillable Bonus Velleda Liquid Tank black P12 is a liquid-ink whiteboard marker designed for writing and drawing on non-porous surfaces such as whiteboards, glass and laminated boards. The marker contains a visible black liquid ink reservoir and a tip engineered to produce clear, consistent strokes suitable for notes, diagrams and presentations. It is intended for office, school and presentation use where erasable, high-contrast markings are required.

Advantages

The refillable liquid tank system provides longer usable life and reduces the need for frequent replacements. Black liquid ink delivers high contrast and improved legibility on light surfaces. The tip shape is optimized for controlled ink flow and consistent line width, enabling clear writing and drawing. The marker is designed for easy refilling and maintenance, which supports cost-effective, sustainable use in environments with regular whiteboard activity.

Suitable for

• Office meetings and conference room presentations
• Classroom instruction and student use
• Training sessions and workshops
• Brainstorming and whiteboard planning

Key specifications

• Ink type: liquid ink formulated for non-porous surfaces
• Ink colour: black for high-contrast markings
• Tip: P12 tip designed for clear, consistent strokes
• Body: refillable reservoir (liquid tank) for extended use
• Surface compatibility: whiteboards, glass, laminated surfaces and other non-porous materials

How to use

Shake the marker gently if recommended by the manufacturer, then press the tip briefly on the writing surface to prime ink flow if necessary. Write or draw as needed on a clean, dry non-porous surface and erase with a standard dry or damp eraser. When ink levels are low, follow the refill procedure using compatible liquid ink designed for whiteboard markers: open the refill port or remove the cap according to the marker design, add the specified amount of refill ink into the reservoir, reseal and allow ink to distribute before use. Clean the tip periodically by wiping with a lint-free cloth to maintain consistent lines.

Usage recommendations

Store horizontally or with the tip down during extended non-use to maintain immediate ink flow. Use only appropriate whiteboard ink refills to prevent clogging and preserve erasability. Avoid using on porous surfaces or permanent surfaces to prevent staining.
