The pictures below give a basic idea of how marking chalk works and why Keson chalk is the best marking chalk in the world. It sticks to your line until you decide you want it to stick to something else. Over the years, we’ve fine tuned our formulas to produce chalk that performs with consistent excellence, batch after batch.
