Spray Chalk

Similar in composition to regular chalk, Spray Chalk is the ideal crime scene marking solution. When applied to a surface, it leaves a bright, easily visible and non-permanent fluorescent mark behind. Spray Chalk will adhere to nearly any surface, including asphalt, concrete, brick, wood, grass and metal. Spray Chalk is applied similar to a can of spray paint. However, when finished, it simply washes off with water.
