These Keson Red Lumber Crayons are the ideal choice for marking layout lines and making notations on materials, such as metal, lumber, concrete, wood, and almost any other surface. The red crayon is great for marking on lighter species of lumber/wood, as the darker color will stand out better on the light wood/material. The crayon is clay-based and won’t penetrate the surface or smudge, and they write easily on rough or smooth surfaces.
The Keson Red Lumber Crayons work well for rough works and marking component pieces. The larger tips are not suited well for finer layout lines. They are designed to work in almost all conditions: hot, cold, wet, or dry. They work well between -20° F to 150° F. Box of 12
