Nobo Glass Whiteboard Markers - Pack of 4

These markers are specifically optimised for glass surfaces. While they may write on other non-porous surfaces, their erasing performance and ink behaviour are best guaranteed on glass whiteboards.

Always recap the markers tightly after each use and store them horizontally or tip-down to maintain ink flow. Avoid leaving them uncapped for extended periods.

The markers feature a 3mm bullet tip, which is designed to create consistent, thick lines suitable for clear visibility.

Each pack contains four markers in assorted colours: Black, Blue, Green, and Red.

These markers are optimized for glass. For painted wall whiteboards, it is generally recommended to use markers specifically designed for that surface type to ensure proper erasability and prevent damage.

Each marker has a unique reservoir design that includes an ink gauge, allowing you to visually check the remaining ink level.

Ensure the cap was replaced properly. If it was, and the ink gauge shows it's empty, the marker has reached the end of its life. If the gauge indicates ink but it's still not writing, try gently shaking it or contacting customer support.

Ensure the cap has been replaced properly after the last use. Try gently shaking the marker. If the issue persists, the ink may be depleted; check the ink gauge.

Allow the ink to dry completely before touching or erasing. This typically takes a few seconds. Ensure you are using the markers on a clean, dry glass surface.

This is unlikely on a suitable glass surface if erased promptly. If marks are persistent, use a dedicated whiteboard cleaner and a soft cloth. Ensure the board surface is not damaged or coated with other substances.
