Features: 1. Alkaline water: Make the drinking water to be alkaline, neutralizes human body's acidic substances and keep balance of the body system. Maintain a healthy pH figure and protect liver from the harm that nicotine and alcohol might do. 2. Negative potential water: Normal water will be adjusted to be negative potential water with an ORP below than 200mVin about 3-5 minutes. It is a strong anti-oxidant which removes free radicals, enhance immunity and keep us from aging. 3. Add beneficial microelements: Various natural mineral substances are set out which provide body with necessary microelements and improve every organs to grow healthy. 4. Energizes water with small molecular clusters structure: With strong osmosis, diffusibility and oxygen-affinity, the energized water bringing nutrient and more oxygen is easily absorbed into the body cells, and easily takes the waste and toxins from our body cells. It quite improves metabolism. Size:Height:136mm,Diameter:17mm Exterior of stick:304stainless steel Interior of stick:tormaline stone,Maifanshi-stone,Farinfrared stone,nano silver powder.
