Here's a blast from the past - 20+ years old - old stock from Excalibur Hotel - I carried these bracelets - this one is still in the original package. I do not believe that magnets work for everyone but for me they did. I was in a horrible car wreck and got involved with them. It has something to do with blood and circulation. Not an expert by any means whatsoever. Just personal experience. I have a few other styles - all new magnetic items. This one is a polished silver plate and solid copper.
