The MAGNALINX MED+RAP is comprised of 60 individual magnets.  It can be adjusted to fit any size wrist up to 9 1/2" by just removing individual magnets.  The individual magnets are 10mm (.4 inches) in height and have a power rating 6,000 Gauss (gauss is how you measure a magnets strength) each.  The SILVER finish offered above is our most popular design for men, women and children alike. When you must have two bracelets, make sure you buy one of these, as it looks fantastic when combined with any of our other MED+RAP finishes.
