I have a nickel sensitivity myself and I now use a brush on allergy shield product...(called Jewlelry Shield ) It looks like nail polish and brushes on the same way. It is sold at Fusion beads, Fire Mountain gems and probably other places but these are the places I use most often. I have had very good luck with it and now I can use base metal findings, even ear wires. *which is nice as I have been partially laid off
