Irwin Strait-Line Marking Chalk White 5lbs

IRWIN STRAIT-LINE® Marking chalks have a newly engineered flip-top cap that keeps the chalk in the bottle where you want it and stops it from spilling out in areas that you don t. The flip-top cap available on all IRWIN STRAIT-LINE® chalk bottles seals the chalk in an air-tight chamber keeping out moisture and reducing the risk of clumping.
