Thank you for viewing. I opened a salon two years ago, but I am selling this item due to the closure of the salon. It has been used frequently, but there are no noticeable scratches or cracks. It comes with a dedicated bag, but it is a little dirty. This is a Gua Sha made of cube-shaped terra-ore. It emits terahertz waves, which vibrate cells and work deep within the body. It vibrates at an invisible speed, so it's interesting to see ice melt rapidly when placed on it. Therefore, it works similarly on the body, approaching cold and stiffened fat. It can be used on the face, head, shoulders, and the entire body, providing a very pleasant feeling. It leaves both the body and mind feeling refreshed. I am selling it for half the retail price. Please use it as a companion for beauty and health.
