The Sienna Bracelet has been designed to bring you the benefits of magnetic therapy in an elegant piece of jewellery and can be worn continuously. The Sienna Bracelet contains powerful neodymium magnets. These will have a penetration area of over 1 inch. Whilst specifically designed to bring relief from pain and discomfort to the wrist and hand, over a period of time, the magnets will encourage your body and blood to operate at a generally more efficient level.
