Money Detective Pen

This pen contains a specially formulated chemical solution that allows the user to verify $1, $5, $10, $20, $50, and $100 bills. Just apply the pen's tip to the currency and press down to release its liquid chemical. A gold "ink" mark verifies legal tender and will disappear in a few days. A black mark warns of a suspect bill and stays until the bill is destroyed. An easy and safe to protect your business against counterfeit bills!
