Product Information

Full details

The Uni-ball Posca 1M marker pens are an essential tool for artists, crafters, and hobbyists who require high-precision, paint-based application on diverse surfaces. These markers deliver opaque, vibrant pigment that works equally well on wood, metal, glass, fabric, and paper, making them a versatile choice for mixed-media projects. While they provide excellent durability and fade resistance, users should note that the extra-fine 1M tip requires a steady hand and proper priming to ensure consistent flow during detailed work.

FAQs

Are these markers permanent?

They are permanent on porous surfaces like paper and wood, and can be made permanent on glass or plastic by baking or sealing, and on fabric by heat-setting.

Can I use these on clothes?

Yes, they work well on fabric. For best results, iron the reverse side of the fabric once the paint is fully dry to set the color.

Do I need to seal my work?

While the paint is water-resistant, applying a clear acrylic spray sealer is recommended for high-traffic items to prevent scratching.

Can I blend colors?

Yes, while the paint is still wet, you can use a brush or a blending tool to mix colors directly on the surface.

How do I store them?

Store them horizontally to keep the ink flow consistent for the fine 1M tip.

Troubleshooting

The marker is not flowing ink.

Shake the pen thoroughly for 30 seconds and repeat the priming process by pressing the nib on a scrap surface.

The tip is dried out or scratchy.

Gently rinse the nib under warm water and blot it dry, then re-prime it until the ink flows smoothly.

The ink is pooling or blobbing.

Do not press too hard on the tip; use a light touch to control the flow and keep the pen at a slight angle.

Pros and Cons

Pros

  • Excellent opacity on dark and light surfaces
  • Extra-fine tip is perfect for complex illustrations
  • Non-toxic and acid-free formulation
  • Durable water-resistant finish after drying
  • Highly versatile across multiple material types

Cons

  • Small tip can clog if not stored correctly
  • Requires shaking and priming before use
  • Not suitable for wide-area coverage due to thin tip
  • Can be difficult to remove from porous surfaces once set

Setup, Compatibility & Care

To get the best results, always shake the marker vigorously with the cap on to mix the internal agitator ball. On first use, press the tip down repeatedly on a scrap piece of paper until the ink flows into the nib. After use, always snap the cap on tightly to prevent the paint from drying out inside the fine tip. If the tip feels dry, you can rinse it with warm water or soak it for a few minutes. Store markers horizontally to ensure equal ink distribution to both ends of the internal reservoir.
