Resonator Processed "To-tonoeru" Ring A silicon rubber ring that uses resonator processing to create a fine, precise, high-speed vibration, forming a well-ordered toroidal magnetic field, and harmonizing distorted electromagnetic waves to condition matter. For those who cannot use wristbands at work. For those who want to improve their body's balance. Use it on your wrists or ankles when you have pain in your hands or feet. I use it on both of my feet, and it has alleviated numbness and fatigue. However, this product does not guarantee any effects, so please purchase only if you understand this.
