This is a solid stainless steel magnetic anklet. This solidly deigned nickel free magnetic anklet has a powerful & permanent 3300 gauss neodymium rare earth north facing magnet in each link. Because it is solidly designed, it is not ideal for petite ankles. This matte silver stainless steel anklet is about 1/3" wide and 1/7" thick. This anklet closes securely with a snap shut clasp.
