Our very best Big Island Koa inlayed into a tungsten link bracelet. 10 magnets are inlayed on the inside of the links to promote health and longevity...if your into that sort of thing : ). Our bracelets are available in 8mm or 10mm wide and have removable links so you can adjust it to your preferred size. The band is 8.5" long when laid flat. Note.. 8mm pictured, 10mm is just slightly wider.
