Its 25 ml capacity reduces the frequency of replacements compared to smaller refills, while compatibility with multiple Edding marker models makes it a practical choice for workplaces and home use.

How to use

Before refilling, ensure the marker body is clean and the tip is in place. Insert the refill nozzle into the marker’s ink chamber according to the marker manufacturer’s instructions and press gently to transfer ink. Allow the ink to distribute through the tip for a few minutes before writing. After refilling, store the marker horizontally or with the tip facing down for optimal ink flow.

Recommendations

Use the refill with compatible Edding markers only. Store the refill capped and upright in a cool, dry place away from direct sunlight. If marks appear faint after refilling, wait a short time for the ink to saturate the tip or perform several test strokes on scrap material. Avoid use on porous surfaces where permanent marker ink may bleed excessively.
