Comments about MMF Counterfeit Money Detector Pens; 3 Pack:
We bought this item as my son was doing a large cash sale with his car and we didn't know who we'd be dealing with. The marker worked very well and i noticed when i went into the bank to deposit the money they used the same one. Would recommend this product if you need to be sure on authenticity.
Bottom Line Yes, I would recommend this to a friend
