Our Black Lumber Crayon Marker is for marking doors and entries for schools and Urban Search & Rescue Teams and CERT Teams. An essential part of each Search & Rescue team is the ability to mark and track their search areas. The marking of search entry points should not slow down the search and rescue effort. You must be able to mark and document your doors quickly and more importantly it must be legible. Black is the most visible color on most exterior surfaces.
This lumber crayon is very durable. It won't melt in direct sunlight, is waterproof and will even write on wet surfaces and won't smear. It will write on wood, concrete, plastic and most other surfaces. And the best part is, if you break your lumber crayon, you now have two! You can't beat that.
