Chalk marker Uni Uni-Ball ChalkGlass PWE-8K — Silver chisel tip 8 mm, 1 pc

Uni-Ball ChalkGlass PWE-8K is a silver chalk marker with an 8 mm chisel tip designed for writing on non-porous surfaces such as glass, chalkboards and smooth signage. The opaque metallic water-based ink produces bold, high-visibility strokes that wipe off from smooth surfaces, making the marker suitable for shop displays, menus, pub and restaurant signs, and craft projects. Supplied as a single pen with a chisel tip for variable-width lettering.

Advantages

The water-based opaque metallic ink creates bright, highly visible lines on smooth surfaces while remaining erasable with a damp cloth. The 8 mm chisel tip allows for thick, bold strokes and variable line widths for large-format writing and hand-lettering. The marker works on glass and chalkboards and is suitable for temporary outdoor signage thanks to reasonable rain resistance on non-porous surfaces.

Suitable for

• Shop displays and window lettering
• Menus, pub and restaurant signs
• Large-format hand-lettering and chalkboard art
• Temporary event signage and decorative craft projects

When it may not be suitable

This marker is not suitable for porous surfaces such as paper, untreated wood, fabric or unsealed stone because the ink is designed for non-porous substrates and will not wipe off from absorbent materials. It is also not intended for permanent outdoor use or on uneven textured surfaces where ink may not form a consistent line.

Key specifications

• Tip type: 8 mm chisel tip for variable-width strokes
• Ink: opaque metallic, water-based paint-like ink
• Colour: silver
• Suitable surfaces: non-porous surfaces such as glass and chalkboards
• Pack quantity: 1 pen

How to use

Shake the pen well before use to mix the metallic ink. Press the tip gently on scrap material to start the flow if necessary. Write on clean, dry, non-porous surfaces and allow a short drying time. To remove, wipe with a damp cloth or non-abrasive cleaner; for stubborn marks, repeat wiping or use a suitable glass cleaner.

What to consider before purchase

• Intended surface: only use on non-porous surfaces like glass and chalkboards
• Removability: ink is erasable from smooth, non-absorbent surfaces but not from porous materials
• Tip size: 8 mm chisel tip produces thick strokes—choose for bold lettering and large-format work
• Outdoor use: limited rain resistance; avoid prolonged exposure to heavy weather

Usage recommendations

For best results clean the surface before writing, test the marker on a small area, and store horizontally when not in use to maintain even ink flow. Replace the cap after use to prevent the tip from drying out.
