Product Information

Full details

The Pentel MWL5SBF-AX is a pack of 12 black whiteboard markers designed for frequent use on white or porcelain boards. Its key benefit is the unique pump-action system that replenishes ink for consistent, vivid lines. A potential caveat is that the line width is variable, depending on the angle and pressure applied, making it best suited for users who can adapt to this dynamic tip.

FAQs

How do I ensure consistent ink flow?

Utilize the pump-action system by pressing the tip down on the board or paper to refresh the ink supply. Store the markers horizontally or tip-down when not in use.

What surfaces can I use this marker on?

This marker is specifically designed for use on whiteboards and porcelain boards. Avoid using it on porous surfaces or glass, as it may not erase properly.

How do I get different line widths?

The flexible brush tip allows for variable line widths. Adjust the angle at which you hold the marker and the amount of pressure you apply to create thicker or thinner lines.

How many markers are in a pack?

This product, MWL5SBF-AX, comes as a pack of 12 black markers.

Is the ink waterproof?

No, the ink is not waterproof. It is designed to be easily erasable with a dry cloth or whiteboard eraser.

Can I refill these markers?

The markers feature a pump-action system to replenish the ink supply, extending their usability. They are not designed for traditional ink refilling.

Troubleshooting

Marker not writing or writing faintly.

Activate the pump-action system by pressing the tip firmly on a piece of paper or scrap board to replenish the ink supply. Ensure the marker is stored correctly (horizontally or tip-down).

Ink smudging after writing.

Allow the ink to dry completely before touching the writing. Ensure you are using the marker on a compatible whiteboard or porcelain surface.

Difficulty erasing markings.

Ensure you are using a clean, dry whiteboard eraser. For stubborn marks, use a dedicated whiteboard cleaner. Do not let markings sit on the board for extended periods.

Pros and Cons

Pros

  • Consistent ink flow thanks to the pump-action system.
  • Vivid and bold writing on suitable surfaces.
  • Versatile line width adapts to different writing styles.
  • Easy to erase without leaving residue.
  • Cost-effective pack of 12 for multiple users or frequent replacement.

Cons

Setup, Compatibility & Care

Setup:

For first-time use, or if the ink flow seems light, you may need to activate the pump-action system. Place the marker tip on a piece of paper or scrap board and press down firmly. You should feel a slight click or resistance as the ink is drawn into the tip.

Compatibility:

  • Recommended Surfaces: Whiteboards and porcelain boards.
  • Not Recommended: Non-porous surfaces like glass (may be difficult to erase) or porous surfaces like paper (ink will bleed and not erase).

Care:

  • Storage: Store the marker horizontally or tip-down to ensure optimal ink flow.
  • Tip Maintenance: If the tip becomes dry, re-prime using the pump-action method.
  • Cleaning: Ensure whiteboard surfaces are clean before use to prevent ink buildup. Erase markings promptly after use for best results.
