Strait-line 8 Oz Standard Marking Chalk Blue 1 Pk

Description

Irwin Strait Line 8 oz. Blue Powder Chalk in a plastic bottle is a high-quality chalk that is perfect for marking lines on a variety of surfaces. It is made from calcium carbonate and ultramarine B, and has a specific gravity of 2.7 to 2.71 and a relative density of 2.7 to 2.71. The pH range is 8.5 to 9.5. This chalk is odorless and comes in a convenient 8 oz. plastic bottle. 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.
