C-FY-1379 Euro Pen Money Tester
One more tool to detect counterfeit bills.
This Pen is specially for all Currency.
Mark the note,for example,with a cross,in an area which is lightly-coloured and not printed on.
If the marking shows up as bright yellow,your bank note is genuine and therefore valid.
If the marking goes dark and stays dark,your banknote is forged.
The marking disappears again a few hours.
