Marking Chalk, Standard, 8 oz Container, 8-1/2 to 9-1/2, Odorless

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 STRAITLINE chalk bottles, seals the chalk in an airtight chamber, keeping out moisture and reducing the risk of clumping.
