Irwin Strait-line 8 Oz. Permanent Marking Chalk Fluorescent Orange

Irwin Strait-Line Marking Chalk Refill is a fluorescent orange powder chalk designed for professional marking and layout work. This micro-fine chalk formula creates visible lines on both hard and soft surfaces, making it ideal for snap lines, foundation marking, design adjustments, and layout corrections.

The 8 oz. plastic squeeze bottle packaging makes application easy and controlled. The newly engineered flip-top cap is a standout feature—it keeps chalk contained in the bottle and prevents spills. This cap seals the chalk in an air-tight chamber, which keeps out moisture and reduces the risk of clumping.
