If the copper wrist bands cured arthritis all’s fair in the selling department!!..right?

Now they put the copper in stockings and elastic support sleeves and claim cure-all.

The FDA cracked down. The copper is now claimed specifically for odor reduction.

But I'm sure the companies are subtly implying that "copper cures arthritis", or at least playing off memories of that [undocumented] belief.
