Irwin Strait Line Blue Lumber Crayon

Marks hold up when the surface does not.

A tough blue crayon for rough jobs and clean, steady marks.

Product Overview:

When you need a lumber crayon that stays put, this one earns its keep fast. The blue mark shows up on wood, concrete, metal, rubber, plastic, cardboard, and ceramic, even when things are oily, slick, wet, cold, or just plain awkward. It is wax based and nontoxic, so it fits the day to day grind without making a fuss. If you are laying out stock, tagging parts, or marking jobs around the shop, you get a simple tool that feels steady in your hand and leaves a clear line you can trust. Picture the mark, hear the quiet scratch, then move on without having to go back and do it twice.

Key Features:

• Waterproof marking keeps your layout visible on damp work, so you are not chasing faded lines.
• Works on slick and oily surfaces and still leaves a readable mark, which saves a bit of cursing.
• Handles cold, wet, and dry materials with the same steady result, so the job keeps moving.
• Wax based and nontoxic gives you a practical marking option that feels easy to use around the shop.
• Blue color stands out well on common jobsite materials, making your marks easier to spot at a glance.
