Review (5/5): Works fast and will save me from my allergies.
So I had this awesome vintage necklace.... after wearing it for 4 hours, I took it off to find a small rash. Well the rash grew all over my neck, up my face and was immensely itchy and painful. I ended up going to urgent care and after having to get 3 different medications for a nickel allergy, I decided to purchase this kit to test the necklace just to be sure (because it is really cute). I got it today and tested the necklace. The white swab part didn't just turn red, it immediately turned red. The whole necklace is loaded with nickel. I'm really happy to have a kit now to let me know before I go and buy any more vintage jewelry.
