Irwin STRAIT-LINEĀ® 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-LINEĀ® chalk bottles, seals the chalk in an air-tight chamber, keeping out moisture and reducing the risk of clumping.

  • For interior and exterior use
  • Marks are temporary
  • Provides great visibility
