Dri Mark CFD5PK Counterfeit Bill Detector Marker Pen, Made in The USA, 3 Times More Ink, Pocket Size, Fake Money Checker - Money Loss Prevention Tester & Fraud Protection for U.S. Currency (Pack of 5)

Works great and last very long. Made in U.S.A. I recommend it for you to have it in your business.

They work well, I've been using the same one for the past couple months and it's still working without issues, and I have the other 4. I consider it a good deal. You wont need to buy more for a while if you get the 5 pack.

Works well, lasts long, and the top stays on.

Works well. Exactly as described. Very affordable.

Works Great

Works very well.

Mis clientas en ocasiones me pagan en efectivo y este set ha sido muy útil. Trae varios plumones, así que pude darle uno a cada una de mis compañeras. Funciona perfectamente y nos da tranquilidad al momento de recibir el dinero. Es un pequeño detalle, pero al final nos evita muchos problemas. Muy necesario para nosotras y totalmente recomendado.

They work great. Shipping was super fast

Works as advertised

The product works. We've used it in our workplace and found fake bills. Love this and woild buy again.
