A simple way to check for suspect counterfeit bills. Just mark the note with a quick pen stroke and check the mark's color. If the special ink turns light brown the note passes; darker brown indicates it is suspect. Agion releases antimicrobial agents when conditions for bacterial growth develop for ongoing protection against bacterial transfer between pen users. Counterfeit bill detector type: pen; marking color: amber; counterfeit indication mark: black/brown; currency: us.
