ZZap Counterfeit Bank Note Detector Pens D1 (Pack of 10)

Firmly established as one of the most accurate counterfeit note detecting pens, the ZZap D1 instantly verifies the authenticity of almost all world bank notes. Using an intelligent iodine-based ink, the pen works by reacting with starch found in standard papers which are not found on genuine cotton or polymer based bank notes. If counterfeit, a highly visible black mark is left on the note. Due to the pen's light weight and small size, it's the perfect fraud prevention tool when mobile catering or at smaller sites where space is at a premium.
