a test for what?

My ears are (were?) sensitive and that is one of the major reasons why I never wear earrings. So far so good though! These are "nickel free"

oh, well then yay!! i wear piercing studs all the time, for the "just in case i have to really wear earrings" reasoning

except for when skating of course!!

she will be doing the same now that she has determined she has a nickel allergy.
