WCRINVO, Bright White Invisible Fluorescent Crayon
Bright White Invisible Fluorescent Crayon.
Our crayons are a popular item to invisibly mark articles such as currency, tires, paper, wood, metal, glass, etc., for identification and thief detection purposes.
They are practically invisible on most backgrounds, but highly fluorescent when exposed to a long or short wave UV lamp.
