ALL MARKING CHALK IS NOT CREATED EQUAL
Keson is the only company making marking chalk in the United States. We have formulated our colors to meet the diverse needs of our customers. The color and the amount of the pigment determines the vividness and permanence of the line.
ProChalk Semi-Permanent for weather- and water-resistant lines that hit and stick for a long time but will eventually wear away naturally. ProChalk Permanent for weatherproof and waterproof lines that aren’t going to go away any time soon.
