FAQs

Can I use the N850 on glossy surfaces?

Yes, the permanent ink is designed to adhere effectively to non-porous materials like glass, plastic, and metal.

Is the ink waterproof?

The N850 uses permanent ink that is resistant to water and smearing once fully dried.

What is the line width of the marker?

The bullet tip provides a precise 2.1mm line width.

How should I store these markers?

Store them horizontally to keep the ink flow consistent across the internal valve system.

Can the ink be removed if I make a mistake?

Because it is a permanent marker, it is designed for longevity, but some solvents like rubbing alcohol may help remove marks from certain non-porous surfaces.

Troubleshooting

Marker is not writing clearly

Shake the marker gently with the cap on to mix the ink, then depress the nib repeatedly on a piece of scratch paper to reactivate flow.

Ink is drying out too quickly

Ensure the cap is snapped on securely after every use and store the marker horizontally.

Pros and Cons

Pros

  • Reliable marking on non-porous surfaces like glass and metal
  • Fast-drying ink prevents accidental smudging
  • Anti-roll cap design keeps the marker in place
  • Consistent ink flow due to valve control mechanism

Cons

  • Requires careful capping to prevent tip dry-out
  • Bullet tip may not be suitable for broad-area filling
  • Permanent ink can be difficult to remove from unintended surfaces

Setup, Compatibility & Care

To ensure the longevity of your Pentel N850, store the marker in a horizontal position whenever possible. This prevents the ink from pooling at one end or drying out at the tip. Always ensure the cap is pressed firmly until you hear a click to maintain the airtight seal necessary for the low-odour ink. If the tip does become dry from exposure to air, you can sometimes restore flow by lightly dabbing it on a piece of scrap paper or by replacing the cap and waiting for the ink to resaturate the nib. The marker is compatible with most standard industrial surfaces; however, it is recommended to perform a small spot test on delicate plastics before full-scale application.
