Setup, Compatibility & Care
To ensure the longevity of your Bi-Office Inkstring XL markers, store them horizontally when not in use to keep the gel ink evenly distributed at the tip. These markers are designed specifically for whiteboards and glass boards; avoid using them on paper or porous materials as the ink may bleed or become permanent. Always press the cap firmly until it clicks to prevent the tip from drying out. To clean your writing surface, use a standard felt or microfiber dry eraser; because of the advanced formula, even basic erasers will remove the marks effectively without needing chemical cleaning sprays.
