How to use To use the Roko black whiteboard marker effectively: Remove the cap: remove the cap before starting to write. Writing: use the pen to write or draw on a clean, dry whiteboard surface. Erasing: writing can be easily erased with a dry whiteboard eraser or a soft, dry or slightly damp cloth. Re-capping: ensure the pen is tightly capped after use to prevent the ink from drying out. Warnings To ensure safety and preserve the pen and surfaces, the following should be observed: Intended use: the pen is designed for use on wipeable whiteboards only. Avoid using it on fabrics, walls, or other permanent surfaces, as stains may be difficult to remove. Avoid swallowing: the ink is not edible, and pens should be kept out of reach of young children. Ventilation: it is preferable to use it in well-ventilated areas. Storage: store the pen horizontally to help the ink flow evenly and prevent drying, and make sure to tightly close the cap when not in use. Stain cleaning: if clothes or fabrics are stained with ink, alcohol-based solutions or liquid soap and warm water can be used to try to remove the stain, with caution not to scrub the stain strongly to prevent spreading.
