Well worth the money
I own a small clothing business and recently I have been having trouble picking out the counterfeit bills. I decided to purchase these to fight the problem. They are very simple to use and when marked on a counterfeit bill it makes an obvious dark mark. It has saved me from accepting numerous 50 dollar and 100 bills since I have purchased it. Well worth it. Also the prices on Amazon can't be beat. At a local store I found them at more than double the cost on Amazon. I would buy them again.

Great pens that save you money in the long run!
We've got a big counterfeit bill problem in the city where I work, so we decided to start checking. I priced these pens at a few big box stores and they all wanted a ton of money for just 2 or 3 pens. Luckily I stumbled across these on Amazon. I gave them out to all our drivers and they certainly work--they've kept us from accepting at least 6 counterfeits in the past month. A solid product at a good price.

Totally worth the higher cost!!!
In my business we go through money markers constantly. The average one will last 5-7 days before drying out. Drimarks last right around 3 weeks without starting to fade at all. They are a bit more expensive than others you will find on amazon but they’re half what they cost at Office Max or Staples. I’ll pay the higher cost for a better product every time.
