Irwin 2032160 Permanent Marking Chalk Refill

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. The Irwin STRAIT-LINE® range of category-leading marking products include dust-off chalk and permanent staining chalk. Dust-off chalk is temporary chalk that can be used to mark interior walls and trim and then wiped away cleanly. Permanent staining chalk is great for extreme outdoor conditions because it can withstand harsh weather conditions and months of jobsite wear. In addition to dust-off and permanent staining, the range of chalk has varying levels of permanence, color and special uses. So whether working indoors or outdoors, on finished surfaces or in extreme conditions, Irwin STRAIT-LINE® has the ideal chalk for every job.
