Thank you for viewing! A highly sought-after power stone that melts ice. This is a set of 2 high-purity 99.9996% Terahertz stone Gua Sha plates. Terahertz ore is a special artificial ore that emits Terahertz waves, a type of electromagnetic wave. Terahertz waves are a unit representing the frequency and vibration that repeats 1 trillion times per second. It is located in the region between far infrared rays and radio waves. It can pass through various substances such as wood and plastic. The phenomenon of "ice placed on Terahertz melting in an instant" is well known, and this is because Terahertz ore has a very high thermal conductivity. It improves stiffness and blood flow, and eliminates the buildup of waste products and fluids that cause swelling. It is a popular power stone in medical institutions and the fashion industry.
