Review (4/5): Works and makes buying jewelry less of a guessing game
I just recently found out I have a Nickel allergy. According to my dermatologist, both "real" and costume jewelry can have Nickel mixed into the metal (along with belt buckles and snaps on pants, etc), so he suggested I buy this to carry with me to test jewelry before I buy it. I just whip this little test kit out of my purse and swab the jewelry before I commit to buying it. The solutions fit into the provided prescription style bottle, along with a few Q-Tip cotton swabs (which you have to provide). All you do is put 2 drops of Solution A and 2 drops of Solution B on the tip of a swab and wipe it across the metal for several seconds. If the swab turns pink (it's not a bright pink, so be sure to look closely), it contains Nickel. This sure beats breaking out into itchy blisters!
