Clear nail polish and a tester that only picks up large amounts of nickel
Waste of money.  It did pick up the nickel in an actual nickel but nothing else.  I even tested items known to have nickel in them and nothing.  I searched and searched for pink and it did nothing.  And the protectant is just clear nail polish!  Seriously, the most expensive nail polish I have ever purchased.  Do not buy this, it will not help you if you have a true nickel allergy.
