This men's or women's copper magnetic bracelet from Sabona features a rope design around the wristband and is made for comfort from 99.99% pure copper. There is a rust resistant 1800 gauss magnet at each tip. Studies have shown that copper can ease the pain of arthritis in some people and that copper absorbed through the skin gets into circulation more efficiently then most dietary copper. Magnets have been used in different cultures to promote good health by increasing circulation which is beneficial because the body will get more of the nutrients it needs from the blood. To get the best fit, subtract 1/2" to 3/4" from your wrist size to determine the size Sabona Copper Wristband you need. Sizes are Medium (6.0"), Large (6.5") or Extra Large (7.0"). Wristbands are to be snug, but not tight. If you are in between sizes, it works better for the band to be smaller rather than larger. Made in the USA.
