Waste of money.
Stay away from these. They turn black with a few drops of water. Don't waste your mkney. Toxins can only be released 2 ways from yoir body: 1. kidneys 2. liver.
Great within 2hours of having them on they showed up some black not sure if everyone gets the same result but that 's what I got really happy so ordered a new batch but the second batch were not so good they were stuck together and I could not peel them off properly so overall only used about 5 of them.
Good but plasters aren't good.
I put these ony feet over night. The adhesive plaster kept them in place. When I took them off the next day the pads had gone from white to black. It was disgusting, but just showed what was in my body.
