The uni-ball PWE5M/8 PF chalk marker set offers a professional solution for creating vibrant, high-contrast displays on non-porous surfaces. This set includes eight assorted colors, allowing for versatile design options on glass, mirrors, and traditional or liquid chalkboards. The markers are engineered with a durable round tip that delivers a consistent line width between 1.7 mm and 2.5 mm, ensuring both precision for detailed lettering and bold coverage for eye-catching signage.

Advantages

These chalk markers provide excellent opacity and smooth ink flow, which makes them stand out against dark or transparent backgrounds. The water-based pigment ink is designed to adhere well to smooth surfaces while remaining easily removable. Users benefit from the convenience of a quick-drying formula that resists smudging during use, yet wipes away cleanly with a simple damp cloth, making it perfect for frequently updated displays.

Suitable for

• Retail store window displays and promotional signage
• Restaurant and cafe menu boards
• Decorative home projects on mirrors or glass
• Temporary labeling on non-porous containers
• Creative arts and crafts projects

When it may not be suitable

These markers are not intended for use on porous surfaces such as paper, cardboard, untreated wood, or fabrics, as the ink will be absorbed and cannot be erased. They are also not recommended for outdoor surfaces exposed to heavy rain, as the water-based ink is designed to be removed with moisture.

Key specifications

• Tip type: Round tip
• Line width: 1.7 mm to 2.5 mm
• Ink type: Water-based pigment ink
• Surface compatibility: Non-porous surfaces (glass, mirrors, chalkboards)
• Quantity: 8 assorted colors

How to use

To begin using the markers, shake the pen well with the cap on to mix the pigment. Remove the cap and press the tip down repeatedly on a scrap piece of paper until the ink begins to flow into the nib. Once the tip is saturated, you can begin writing or drawing on your chosen surface. When you wish to change your design, simply wipe the surface with a clean, damp cloth to remove the ink completely.

What to consider before purchase

• Ensure your target surface is non-porous to allow for easy erasure
• Test the marker on a small, inconspicuous area if you are unsure about the surface material
• Store the markers in a horizontal position to maintain optimal ink flow

Usage recommendations

For the best results, always store the markers horizontally and ensure the cap is tightly closed after every use to prevent the tip from drying out. If the tip becomes dry, re-prime it by pressing it against a hard surface until the ink flows again.
