Permanent construction marker GEKO black thick – set of 2

GEKO permanent construction marker black thick – set of 2 is a pair of heavy-duty markers designed for clear, permanent marking on construction materials. The markers contain black, quick-drying ink that remains visible on rough or porous surfaces such as wood, metal, plastic and cardboard. The thick tip produces bold strokes for high visibility and is suitable for indoor and outdoor applications on job sites, workshops and packaging tasks.

Advantages

The set provides two identical markers for continuous work without frequent replacements. The thick tip ensures broad, consistent lines that are easy to read from a distance. Quick-drying, permanent ink reduces smudging and resists fading on most common construction materials. The marker barrel is designed for comfortable hand-hold during extended use and the cap seals securely to help prevent drying between uses.

Suitable for

• Marking timber, plywood and laminated boards

How to use

Shake the marker well before use to mix the ink. Remove the cap and press the tip gently on a scrap surface to initiate ink flow if needed. Draw or write directly onto the target material using steady pressure to produce bold, even strokes. Replace the cap after use to prevent the tip from drying. For best results on very porous or dusty surfaces, clean and dry the area before marking.

Usage recommendations

Store markers horizontally or capped in a cool, dry place away from direct sunlight. Test the marker on a hidden area if marking coated or painted surfaces to check compatibility. For prolonged storage, ensure caps are fully closed to preserve ink life.
