Permanent marker Posterman POSTERMAN BIGGIE 50mm black – broad chisel tip 50 mm, black ink

Posterman POSTERMAN BIGGIE 50mm black is a permanent broad-tip marker with a 50 mm chisel-style nib and black ink made for marking large surfaces. The marker dispenses dense, water-resistant black pigment that produces bold, highly visible strokes on posters, cardboard, corrugated board and other signage materials for both indoor and outdoor use.

Advantages

The 50 mm chisel tip delivers wide, consistent lines and allows for varied stroke widths by changing the angle of the nib. The permanent, quick-drying ink resists smudging and withstands moderate exposure to moisture and fading. The barrel is sized for comfortable grip during extended use and the cap seals securely to maintain tip shape and ink integrity between uses.

Suitable for

• Large-format posters and display boards
• Packaging, crates and corrugated cardboard
• Point-of-sale signage and promotional displays
• Temporary outdoor signs and event wayfinding

Key specifications

• Tip type: chisel (broad)
• Tip width: 50 mm
• Ink color: black
• Ink type: permanent, quick-drying
• Suitable surfaces: paper, cardboard, corrugated board, some plastics and painted surfaces
• Usage environment: indoor and outdoor signage

How to use

Remove the cap and test the marker on a scrap material to confirm stroke width and ink flow. Hold the marker at different angles to create broad fills or narrower edge lines as needed. For best results on absorbent surfaces, apply with steady pressure and allow ink to dry fully before stacking or exposing to moisture. Replace the cap firmly after use to prevent the tip from drying out.

Usage recommendations

Use on clean, dry surfaces and avoid prolonged exposure to direct sunlight to extend visibility. When marking sensitive plastics or glossy finishes, test on an inconspicuous area first. Store horizontally or with the cap secured to preserve tip condition and ink flow.
