A thin layer of concentrated DYETECTIVE
GEL, contains an invisible stain agent which reacts with moisture
in the skin, to produce a stubborn invisible white stain, which is difficult
to remove. Even after repeated washing, it can remain on the skin for up
to 2 days. To view the UV stain, a UV Blacklight is required. The size and longevity of the stain, will depend on
the amount of handling by the thief along with their hand washing
habits.
