Tourma®Bands are tourmaline infused wristbands that come in black. The choices are pairs of medium, pairs of large and single 5.5″ long Tourma®Bands. Tourma®Bands contain nanometer-sized tourmaline particles. Tourmaline particles have been shown to convert body heat into therapeutic far infrared energy. Tourmaline particles also produce negative ions that enhance a more alkaline environment in the body, which encourages accelerated healing, a more rapid recovery from physical activities and also reduces the oxidative stress.
