Tomalin cup, also known as nano-energy cup and calcium carbide health cup. Usually, they are the above three names, and some places call them: negative potential water cup, negative potential nano-energy cup, micro-electrolysis water cup, super micro-electrolysis water machine, weakly alkaline ion water cup, micro-electrolysis water cup, tourmaline active intestine-clearing cup, negative potential water cup, alkaline water cup, micro-electrolysis water cup and weakly alkaline water cup.

The tourmaline energy cup is made of dozens of natural materials, and the Wokang tourmaline water cup is refined by modern cutting-edge nanotechnology. Natural substances in the cup can transform ordinary drinking water poured into the cup into "small molecular group" weakly alkaline water within 15 minutes, and at the same time, it can release far infrared electromagnetic waves, and the water quality, calorific value and activity change, so that ordinary drinking water can be instantly transformed into super living water which is extremely beneficial to human body. Weak alkalinity: remove acidic metabolites in the body, eliminate tobacco poisoning and alcohol poisoning, remove excess fat, adjust the acid-base balance of the human body, and prevent diseases. Small molecular groups: improve human microcirculation, clear the bowels and relax bowels, accelerate the excretion of toxins in the body and promote metabolism. Negative potential: eliminate excess free radicals in the body and delay aging. It is widely used in antimony star.
