As real as it gets
Yep, it’s a real counterfeit pen. Works as it should. Leaves a light yellowish mark on real bills, and a big black mark on fake hundos, as well as the tens tens twenties and the fitty’s.

Pen was dry and bad quality
The pen was terrible and didn’t have much ink in it. I don’t know if it was just old or what, but terrible quality.

Counterfeit pen
Love this especially that it has attachment cord. Here in the airport it can get lost in the mix of things.

The Perfect Solution
This marker has put my mind at ease since I was unable to visually authenticate $100 dollar bills received for spa services

Counterfeit pen
So far, this pen works great. With the uptick in fakes, we thought we should try this pen.

Does the Job
Has sticky tape on the back so you can stick it to your register. Does the job it's supposed to.

Counterfeit pen
Pen does what it supposed to do. I got the pen to check some 20 dollar bills. I recommend this pen. Make sure to place cap back tightly. It seems like it will dry out quickly.

Works fine
Sold a car privately and wanted to make sure a stack of hundreds were all legit...this was a very cheap investment for peace of mind.

Life changing
I purchased these counterfeit pens to replace the UV light that failed me. Unfortunately I was hit with a counterfeit prior to having a pen. Now I feel relaxed knowing it will tell me without guessing.
