The IRWIN® STRAIT-LINE® chalk range has a wide range of permanencies and colors. Whether working indoors or out on finished surfaces or in extreme conditions, IRWIN® STRAIT-LINE® has the ideal chalk for every job. Dust-off chalk is temporary chalk that can be used to mark interior walls and trim and then be wiped away cleanly. 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 do not want. The flip-top cap; available on all IRWIN STRAIT-LINE chalk bottles; seals the chalk in an airtight chamber; keeping out moisture and reducing the risk of clumping.
