Product Description
The IRWIN INDUSTRIAL TOOL CO 66402 is a blue lumber crayon designed for marking on a wide range of job-site surfaces. It writes on oily, slick, wet, cold, and dry surfaces without skipping or smearing. The formulation is non-toxic and waterproof, making it reliable in outdoor and wet-area applications. This crayon is a standard marking tool used by carpenters, framers, concrete finishers, and other trade professionals who need a clear, durable mark that holds up through handling and weather exposure. Each package contains 12 crayons.
The 66402 is suited for use on lumber, concrete, ceramics, and metal covering the most common materials found on residential and commercial job sites. It performs on surfaces that cause standard markers or pencils to fail, including freshly cut or pressure-treated lumber, poured concrete, and coated metal stock. The 12-count packaging makes it practical for crew use or keeping a supply in a service vehicle or tool bag.
