Setup, Compatibility & Care
To ensure the longevity of your Bi-Office Inkstring XL markers, store them horizontally when not in use. This position ensures that the gel ink remains balanced at the nib. These markers are strictly for use on non-porous surfaces; usage on porous materials will cause the ink to bleed and become permanent. When cleaning, if a board has been neglected for a long time, use a dedicated whiteboard cleaning solution before applying fresh ink to ensure a clean surface. Always snap the cap until you hear an audible click to confirm it is airtight.
