Visible theft detection powder will help you find the thief in your midst.
Use a brush to lightly apply the powder to a surface such as a doorknob or a valuable object. When your thief touches the object, the powder reacts with the natural moisture on the hand, causing it to turn a brilliant color. This difficult-to-remove stain easily identifies your thief.
Powders start as one color, and once activated by human perspiration or moisture, they stain as another color. For example, the copper-colored powder turns orange after being touched.
Choose from many color options. Pick a powder color to match the surface where it will be applied.
Comes with a free applicator brush.
