The tourmaline energy health cup is also called the tourmaline energy health cup, and the nano energy cup is referred to as the Ketcom energy cup for short. The tourmaline energy cup is a new type of health-care water cup with a functional area at the bottom. Functional materials are made of tourmaline, activated carbon, volcanic rocks, germanate, activated silica, activated titanium oxide and other dozens of natural materials. , refined from the current nanotechnology. Natural substances in the cup can change ordinary drinking water poured into the cup into "small molecular group" weakly alkaline water within 15 minutes, and the water quality, calorific value and activity have all changed, so some people call it weakly alkaline water cup.
