Midnight Black Permanent Sizes:4 LB Irwin
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.
- Visible after weeks of weather exposure and jobsite wear
- Reduces need for spray sealant
- Stains surfaces
