Visible Thief Detection Powder, Purple, stains PurpleSKU: 7100
Visible Thief Detection Powders and Pastes are designed to be applied to a surface such as a doorknob, tool, cashbox or other object. When the thief touches the object, the powder or paste is transferred to his hands or clothing. The visible powders and pastes come in various colors and can be applied thinly so as to be nearly invisible; but when the powder or paste reacts with moisture or perspiration, it suddenly turns a brilliant visible color thereby marking the thief with a difficult to remove stain. Pastes are particularly useful when object is exposed to weather. Visible thief detection powders and pastes should be used primarily on nonporous objects and may permanently stain porous objects. powders are offered in 1 ounce jars and pastes in 1 ounce tubes.
