Sabona Copper Wristbands are made with the purest copper available-99.99% All styles are designed for comfort and manufactured to maintain shape and quality appearance. 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 Small (5.5"") 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. Copper when in contact with the skin form chelates with human sweat (sometimes seen as a green deposit under the bracelet) and is thus absorbed through the skin. It can be removed with soap and water or lemon juice. To clean your Sabona bracelet use a good jewelry cleaning cloth to keep the outside polished and the inside clean. Your Sabona magnetic bracelet comes packaged in a presentable black jewel box.
