Lumber Marking Crayons

Professional-grade extruded hard lumber marking crayons designed for clear, durable marking on timber, masonry, concrete and steel. Built for demanding industrial environments, they produce bold, highly visible marks that resist smudging, moisture and heat.

The extruded construction ensures superior strength and consistency, allowing the crayon to last significantly longer than ordinary moulded wax crayons while maintaining clean, sharp lines. Ideal for construction, carpentry, sawmills and general site use.
