Premium Formulation: Manufactured using an extruded process that makes each crayon fade-proof, waterproof, and smear-proof. They are temperature-stable and will not soften or melt when exposed to direct sunlight on the job site.

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

Design & Packaging: Formatted into a hexagonal shape (4-1/2" x 1/2") to ensure it won't roll away on sloped surfaces and to guarantee a perfect fit in standard lumber crayon holders. Supplied in a box containing 12 crayons.
