Extreme Weather Permanence: Engineered as a water-proof, scuff-proof, and windproof permanent black marking compound. It binds deeply into porous surfaces like wood and concrete, ensuring your lines remain perfectly intact against punishing downpours and high-traffic job site conditions.

Crisp Line Resolution: Specially formulated to snap clean, solid lines with significantly less smudging than traditional molded or standard chalks, completely removing the need to clear-coat or protect your layout markings.

All-Weather Performance: Can be deployed in high-wind conditions and works seamlessly across both wet and dry applications. For damp materials, simply wipe clear any standing water and snap.

Convenient Clean-Up: While it provides ironclad permanence on building materials, the non-toxic, environmentally friendly formula is specifically engineered to wash easily out of work apparel and off hands using standard mild soap and water.
