Temporary Formula: Engineered explicitly for non-permanent markings. This white formula provides clean contrast on dark materials, brick, and roofing felt, but can be easily brushed away, washed off, or painted over without bleeding through coatings.

Weather-Resistant Build: The durable formula works efficiently for both interior and exterior projects, clinging uniformly to self-chalking line reels to drop crisp guides on lumber, concrete, metal, and drywall.

Airtight Moisture Protection: Packaged in a robust 5 lb. bulk container featuring an advanced flip-top cap. The cap creates an airtight seal that completely locks out job-site humidity, preventing internal clumping and ensuring a smooth, dry flow.
