Ultraviolet Thief Detection Powder

(VPOW)
Visible Stain Thief Detection Powder

This Thief Detection Powder is invisible to the naked eye – so you can mark an item without anybody knowing. Once the powder is touched it remains on fingers and hands for several days and can only be seen by ultraviolet light.

Some situations require visible stain detection rather than ultraviolet detection. This detection powder traps thieves by applying the powder directly to items that are likely to be stolen. When the powder comes in contact with skin, the body’s amino acids react with the powder and create a highly visible purple stain that lasts several days.
