Perco Counterfeit Money Detector Pen - Easy to Use and Reliable Universal Currency Fake Bill Checker for Personal & Commercial Use - Ensures Authenticity & Prevents Fraud

Easy to use. Does what it's supposed to do. No complains. I keep it right in my cash box.

Great price, works well

Used a few times. The last was for a car sell which the buyer had many 100's and 50's. The pen eliminated all worry.

I'll be selling my car shortly and will only accept cash. This will be my first private party car sale and while I am already a little nervous about it, this pen will give me a little extra peace of mind when the time comes and I can use this pen on the cash being offered to make sure it's authentic. When run across the surface of a real bill, it is barely visible but there is a tiny yellow tint where the pen has crossed. A black streak appears almost immediately when it run across anything else that isn't genuine currency. I may never use it again after my car is sold, but I'm glad I came across this product as it will help ease my fears of getting scammed.

i used to do a lot of art markets and handled a lot of cash and always wished i’d had one of these. i do still occasionally get paid in cash by clients so i figured why not. on regular bills, you can barely detect that there is a mark and then it seems to fade away. i of course didn’t have any counterfeit bills so tried it on regular paper, and sure enough, you could see a dark mark. great if you deal with a lot of cash to be able to check, especially large bills. reasonable price.

Works

Every business or person that handles cash should have this. You don't want to be handling fraudulent money. It easily detects fake currency
