The W20 uses dry-erase ink that wipes off quickly with a dry eraser or microfiber cloth on non-porous boards. When used on good-quality boards, ghosting is minimized; using a proper eraser and occasional board cleaner helps keep the surface residue-free.

To refill, use compatible Faber-Castell refills designed for the W20. Replace the ink cartridge as directed by the product instructions, ensure the marker is capped when not in use, and store in a cool, dry place. Refilling reduces waste and ongoing cost.

The W20 is designed for non-porous surfaces such as whiteboards and glass boards. It can be used on other non-porous classroom or office surfaces that accept dry-erase ink, but performance may vary on non-standard surfaces.

Yes, the W20 uses a low-odor, water-based dry-erase ink. It is intended for indoor use in classrooms and office environments. As with any marker, avoid contact with eyes and skin, and keep out of reach of small children who might misuse it.

The marker’s longevity depends on usage patterns. Because it has a refillable body, you can replace the ink rather than disposing of the marker, which improves long-term value and reduces plastic waste compared with disposable markers.

Keep the marker capped when not in use and store in a cool, dry place away from direct heat. While some users store markers horizontally, keeping the cap on prevents ink from drying at the nib.

Refillable markers reduce plastic waste and lower long-term consumable costs. You can keep using the same marker by replenishing the ink, which is both environmentally friendlier and more economical over time.

The W20 sits between the W25 and W40 in line width flexibility. W25 generally offers a finer line for headings and details, while W40 provides broader strokes for bold titles. All share the low-odor dry-erase ink and refillable design.

Angle the marker to draw fine lines (edge of the nib) or lay the chisel flat on the board for broader strokes. Rotating the marker between strokes can help you control line width precisely for headings, grids, and emphasis.

Wipe the board with a dry eraser or microfiber cloth to remove most of the ink, then use a board cleaner or a damp cloth if any stubborn residue remains. Regular cleaning helps prevent ghosting and keeps boards looking clear.
