Irwin Strait-Line 6Orange Hi-Visibility Marking Chalk, 5 Lb.

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 airtight chamber, keeping out moisture and reducing the risk of clumping.
