Yellow Markal Pro-Ex Extruded Clay Based Crayon, 1/2 Hex, 4-5/8 Length (Pack of 12)

Pro-EX is a versatile marking tool that can be used on green and dry wood, lumber, plywood, structural framing, masonry, metals in steel mills, lab shops, and more. Its extruded, clay-based formula offers extended write out, superior strength, water resistance, fade resistance, smear resistance, and exceptional color visibility. This innovative crayon saves on inventory costs by eliminating the need for special lumber crayons for specific applications. Pro-EX is all you need, no more "soft" style crayons necessary.

This high-quality crayon is perfect for marking on wet, frozen, or treated wood, removing the necessity for special "graphite" black lumber crayons. You can use the standard Pro-EX black crayon instead of graphite for applications that require higher temperatures. In addition, Pro-EX is now available in 10 vibrant colors to suit all your marking needs, regardless of the surface or application.

The crayon comes in a standard 1/2" hex shape that fits perfectly in the #109 Peterson holder, #106 holder, and #108 holder. It has a marking range of -20 degrees F to 130 degrees F (-29 degrees C to 54 degrees C) and is available in yellow.

Key features of Pro-EX include the traditional clay-based "feel" that high-volume users prefer, a stronger formula to reduce breakage, and display packs with a convenient tear-off top for individual sales. The crayon measures 4-5/8" in length by 1/2" hex and offers superior performance on wet wood. It is lead-free and extruded to ensure durability and reliability in various conditions.
