Counterfeit Money Detector Pen (2 Counterfeit Pens) - Money Marker Bill Detector Pen with Upgraded Chisel Tip - Detect Fake Bills, Universal False Currency Checker Pack

These pens work great! The price wasn’t bad at all.

Works as described. Easy to use and definitely worked great.

We needed them for a garage sale when people would be bringing larger bills. These worked great

I had received some $100 bills for a car I sold to someone I didn’t know, and used it on them. Worked as stated! And arrived on time.

Was a little surprised at how small these currency detector markers were - but they get the job done quick and easy! As a marketplace seller I encounter a lot of cash sales and its important to have a quick process to make sure the bills used for payment are legit. I tested them on actual bills which leave the light color as well as any other paper which leaves the obvious darker color so they are very accurate. Highly recommended as they are useful to keep your cash transactions secure. Great value.

They are ok, dry out quickly and tips of marker become worn fast. But for the price they got the job done

Not much to say here. They serve their purpose. Easy to use.

Good pen. Will use at upcoming charity sale.
