Dri Mark, DRI3513B, Counterfeit Detector Pens, 3 / Pack, Black

These are good money marker pens, and they last a long time before drying out.

This pen works as it claims to work by the manufacture. I always carry it with me to test money when Im ask for change of bills

These detector pens came in exactly as pictured and they're great. I compared prices to other sellers and brands and these ones seemed like a good price for the pens you get.

Amazing product at a great price!

I am rating the counterfeit end this way because they work amazing and then this day and time they need to get a lot of use. As for Walmart ordering and delivering that is truly truly amazing I don't know how I lived without it !!! I love it !!! If you haven't tried it yet please do you'll be amazed !!!

I've been using the DriMark brand for over 20 years now. It's simple and very reliable to use. I always use this to check my bills to make sure they're legit. I always draw a small mark on the right hand side in a blank area. A yellow mark means it's ok, while a brown/black mark means you might have a questionable/bad bill. It's a useful tool to have when you use/deal with a lot of cash.

These pens work well detecting counterfeit bills .I was amazed and quite pleased ,just a little mark and you know if good or bad.

Ordering was easy, fast, & accurate. Received items a lot faster than we expected. Pick up at the Bremen Store was fast & easy. Loved the items. Exactly what we needed.

We had a garage sale and our local police department warned about counterfeit bill in small denominations such as $5's, $10's and $20's. We did not detect any counterfeit money so I guess these pens worked.

The caps fall off too easily drying out pens so you have to buy more. Planned obsolescence. Add some alchohol to the ends to restart them. They should tell you that at Dri Mark, but of course, they do not. LOL
