Dri Mark CFD5PK 偽造紙幣検出器マーカーペン、米国製、3倍インク、ポケットサイズ、偽造マネーチェッカー-米国通貨の損失防止テスター&詐欺防止(5本パック)

The product works. We've used it in our workplace and found fake bills. Love this and woild buy again.

Great product with a great price that works perfectly detecting counterfeit money. If you leave the USA, grab some of these pens and take with you while traveling abroad to avoid fake US money bills in any of your exchanges on the road. Safe travels. Recommend. 5 stars.

Works as advertised

These markers haven’t failed me yet, so I’d say they’re pretty accurate! It’s simple, if the color is really dark, the bill is fake. If it’s a light tan color, it’s real. I still use these at my business every day. I check everything over a $20 note, and sometimes even on the $20 bills. They’re a bit shorter than a regular sharpie marker but not by much. They seem pretty durable, I’ve used the same marker for about a year now and it hasn’t dried up yet. Great for small business or currency collectors!

Works great and last very long. Made in U.S.A. I recommend it for you to have it in your business.
