Setup Instructions
- Unpack: Carefully remove the markers from the 12-count package. Each marker is individually wrapped in plastic for protection. Remove the plastic wrapping before use.
- Prepare the Tip: The marker tip may appear yellow or uncolored initially. This is normal.
- Prime the Marker: With the cap removed, gently press the marker tip down onto a scrap surface (e.g., paper or cardboard) several times. Hold it down for a few seconds until the paint begins to flow and saturate the tip with green ink. This process may take a moment.
- Test: Once the tip is fully saturated with paint, test the marker on a scrap surface to ensure smooth and consistent ink flow before use on your intended project.

Operating Instructions
The Uni-Ball PX-20 Paint Marker features a versatile medium chisel tip, allowing for both precise lines and broader strokes. Its alcohol-based solvent ensures quick drying time.
- Application: Use the marker for drawing, writing, or marking on a variety of surfaces.
- Surface Compatibility: These markers are suitable for use on leather, stone, wood, metal, vinyl, textile, paper, rubber, and plastics.
- Line Variation: Utilize the chisel tip to create different line widths. Use the narrow edge for fine details and the broad edge for wider coverage.
Maintenance
- Recap After Use: Always replace the cap securely after each use to prevent the paint from drying out.
- Storage: Store markers horizontally at room temperature to ensure even ink distribution and prolong their lifespan.
Troubleshooting
- Ink Not Flowing: If the ink does not flow smoothly, re-prime the marker by gently pressing the tip down on a scrap surface until the paint saturates the tip.
- Dry Tip: If the tip appears dry or damaged, ensure it is properly primed. If priming does not resolve the issue, the marker may need to be replaced.
