D-TEK Counterfeit Pens allow you detect counterfeit currency in seconds. Simply mark the note in question, for example, with a cross in an area that is lightly colored and not printed on. If the marking shows as a bright yellow/amber the note is valid! If the marking goes dark and stays dark the note is forged! Product highlights include highly effective, quick and simple, work on International and US Currency, and antimicrobial protection. This product is PROP 65 compliant.
