A small quantity of this extremely sensitive visible thief detection powder is applied on articles to be handled or tampered with by the suspect thief. The perpetrator can easily be identified by the visible stains on his hands, fingers and clothing which result from direct contact with the powder. Subsequent washing attempts will not remove the stain but will actually intensify the visible stain and usually remains stable for several days. Recommended for indoor applications. Applications include safes, cash boxes, cash registers, lockers, currency boxes, crates, etc. Supplied in 2 ounce volume jar.
