Nadex Counterfeit Pen, Easy Swipe - Gold for Real, Black for Fake, Detect Counterfeit Bills (1 Pack)

Effective when using at work, marked currency effectively.

Pens are great! I just didn’t need so many. They will probably dry up by the time I need one again.. I sold something for a lot of cash and don’t trust anyone in this day and age..

Product works, gold color is faint and hard to see.

Bought this for some cash sales of puppy litter. Worked great and wasn’t dried out as some reviews stated.

I was skeptical due to some reviews stating pens were dried out. Nope, no mine. I tested all pens as soon as they arrived. Good value. Fast delivery.

Work good

Marks about 10 bills per pen. Not happy.

Love it
