Irwin STRAIT-LINE 8 oz. Red Marking Chalk Refill

Irwin STRAIT-LINE marking chalk is designed for creating bold, visible layout lines on exterior surfaces. The bottle features an engineered flip-top cap that keeps the chalk securely contained and prevents accidental spills during storage and transport. The flip-top cap creates an airtight seal that locks out external moisture, reducing the risk of clumping and ensuring smooth, hassle-free dispensing when refilling your chalk lines.
