Premium Formulation: Built using an extruded clay-wax process that makes each crayon fade-proof, waterproof, and smear-proof. They are highly temperature-stable and will not melt or soften when left out in direct sunlight.

Surface Versatility: Designed to write smoothly and leave bright, solid marks on challenging textures including wet (green) lumber, dry wood, structural steel, sheet metal, and concrete.

Design & Packaging: Formatted into a hexagonal shape (4-1/2" x 1/2") to prevent rolling on sloped surfaces and to guarantee a perfect fit in standard lumber crayon holders. Supplied in a bulk box containing 12 crayons.
