Permanent black marking chalk that snaps a bold clean line. Designed for application on porous surfaces such as wood and concrete for the highest level of permanence, outperforming traditional chalk with less smudging.

Permanent red marking chalk, designed for application on cured concrete and wood, dark surfaces, and in low light areas. Redline’s pigment provides a highly visible line for cleaner crisper measurements that last long after the job is done.

Safe & Easy Clean Up.

Our product is virtually permanent on the job site, but is easily washed away from hands and work clothing with mild dish soap, laundry detergent, and water.
