Handy for the Big Yard Sale at Temelec in Sonoma CA
We wondered if we would get any big bills - we did. We wondered if yard sales of this size would bring in folks with counterfeit bills. Well with this pen we didn’t have to worry if someone tried to pass something off on us. The day went smoothly and the marker kept us safe.

Happy with
I am happy with the Dri Mark Smart Money Counterfeit Pen Black 3511B1. I used it for the first time yesterday. Thought I was going to use it for my yard sale but did not. But did use yesterday for a purchase that was made from me. The mark was yellow indicating a good bill. Thank you for selling this item in your store.

Worth it
We had to do an unusually high (for us) cash sale; this was very cheap insurance against a risk we rarely encounter. Worked great and was far quicker easier and less disruptive to just stripe all the bills at once than to inspect each one for security features we're not familiar with.

Counterfeit Marker
I’m happy with this purchase. I sold a pool table and needed a way to make sure all the cash was real. Went to stables got that marker and went home and test it- looks legit. When it came for me to sell the pool table- the buyer gave me the cash I took out the marker spread the cash and marked it fast and all of them was light- easy and simple- I recommend everyone ...
