For warmer climates, Keson lumber crayons can be a perfect choice for industrial or survey marking.
Both waterproof and weatherproof, they provide long-lasting, highly visible marks on any surface under any weather conditions.
Lumber crayons can be purchased in yellow, white, pink, blue, red, green, or black, and are sold by the dozen.
To ease handling and prevent breakage, Sokkia lumber crayon holders feature a wooden handle and twist top to lock the crayon in place. These holders fit all regular brands of lumber crayons.
