Strait-Line 8 Oz Permanent Marking Chalk Blue 1 Pk

Irwin STRAIT-LINE Marking Chalk Refill is a permanent marking solution designed for professionals and DIY enthusiasts who need clear, visible lines that withstand outdoor conditions and jobsite wear. The indigo blue color provides visibility for layout work. This refill bottle is engineered to keep your markings intact even after weeks of exposure to harsh weather, reducing the need for additional protective coatings.

The newly engineered flip-top cap seals the chalk in an air-tight chamber, preventing spills while protecting the chalk from moisture and clumping. This design keeps the chalk in the bottle where you want it and stops it from spilling into areas you don't want.
