FAQs

Can I use these markers on a standard chalkboard?

No, these are designed specifically for non-porous surfaces like glass, metal, and plastic. They may stain or become permanent on porous traditional chalkboards.

Are these markers permanent?

No, the ink is water-soluble. It is resistant to light rain but is designed to be removed easily with a damp cloth.

How do I store the markers to make them last longer?

Keep the markers stored in a horizontal position with the cap tightly secured when not in use.

What is the tip size?

The PWE5M features a medium bullet tip measuring 1.8mm to 2.5mm.

Can these be used on skin?

No, these markers are intended for glass and non-porous surfaces and should not be used on skin.

Is the ink toxic?

Uni-Ball UniChalk markers use water-based ink, but they should always be used in well-ventilated areas and kept away from children.

Troubleshooting

Ink is not flowing to the tip

Ensure the cap is on and shake the marker firmly, then depress the tip repeatedly on a scrap piece of paper until ink saturates the nib.

Marker is difficult to wipe off

Use a slightly warmer damp cloth or a small amount of mild dish soap to help break down the ink pigments on the non-porous surface.

Ink looks faint or streaky

The surface may be slightly porous or dirty; clean the surface thoroughly and apply a second coat once the first layer is dry.

Pros and Cons

Pros

  • Vibrant fluorescent color for high visibility
  • Rain-resistant ink perfect for storefront windows
  • Dust-free alternative to traditional blackboard chalk
  • Easy to remove with water
  • Consistent ink flow with the medium bullet tip

Cons

  • Not suitable for porous surfaces like wood or paper
  • Requires non-porous glass or plastic for optimal performance
  • Not intended for long-term permanent signage

Setup, Compatibility & Care

Before using your markers, ensure the surface is clean, dry, and free of oils or dust to guarantee proper ink adhesion. Store the markers horizontally to keep the ink flow consistent across the bullet tip. If you have been using the markers for an extended period, ensure the cap is replaced tightly after each use to prevent the tip from drying out. When you are ready to change your design, simply use a soft, damp cloth or sponge to wipe the surface clean. Avoid using harsh chemical cleaners, as water is generally sufficient for removal.
