Hiden natural bubble water is used by the royal family of England. The water source is from the chalk hills in southern England, which is located below 70 meters of the ground. After 20-50 years of natural filtration, it is bottled in the water source. Therefore, xiden mineral water is as pure as crystal, pollution-free, high in calcium, stable in composition, and extremely sweet in taste. It uses a unique glass bottle packaging, and can be seen in many high-end restaurants and clubs.
