Marker uni-ball Paint PX-30, chisel tip, black, 1 pc, dimensions 143×23×23 mm

uni-ball Paint PX-30 is a single black oil-based marker with a chisel tip designed to produce opaque, waterproof lines on a wide range of surfaces. The marker measures approximately 143×23×23 mm and features an 8 mm chisel nib that allows both broad strokes and finer edge lines. This marker is suitable for marking, signage, craft projects and any application that requires a bold, lasting black line.

Advantages

The 8 mm chisel tip provides variable stroke widths—from wide fills to narrow edges—without the need to change tools. Compact, single-piece packaging makes it easy to carry or store with other supplies.

How to use

Shake the marker well before use to mix the pigment. Remove the cap and test on scrap material to confirm stroke width and ink flow. Apply with the chisel edge for narrow lines and rotate the tip or lay it flat for broader coverage. Close the cap securely after use to prevent drying. Allow the ink to dry completely on the surface for best waterproof performance.

Usage recommendations

For optimal results, work on clean, dry surfaces and test the marker on an inconspicuous area first. Use light passes when filling large areas to avoid pooling; allow layers to dry between passes. Store horizontally if instructions indicate to maintain consistent ink flow.
