We offer an effective range of Energy Cup (Alkaline Energy Flask) in India. The material is made through scientific method refining. The common purified water is of macromolecule group water with acidity, none of mineral element. If you drink it for long term, the immunity will be brought down. The nanometer Energy Cup can change the common purified water into nanometer activated water by the activation of Pearl calcium ion and Energy stone, which can release far infrared ray and negative ion, thereby causing the synonym of water molecules, releasing mineral element (such as Ca, Mg, K and Na),changing the common purified water into nanometer activated water. The nanometer activated water is made up of macromolecules group, with negative potential, & of alkalescency.
