Copper is a natural anti-oxidant. It helps to strengthen the immune system which leads to faster healing of wounds and cuts. Water stored in a copper jug stays cold for extended hours and the natural anti-bacterial properties of copper destroy any germs or bacteria present in the water. Also, when compared to plastic or steel utensils, water stored in copper utensils stays fresh for longer. This unique set of copper jug and tumblers is specially made for reaping the benefits of copper charged water. The hammering makes the copper pure and also increases the surface area which means more copper is in contact with the water. One common problem faced while using a copper vessel is the discoloration. The way to counter that is to wash your copper utensil with lemon and salt or tamarind regularly. To avoid scratches from normal washing materials, use an old cotton cloth instead. Also, wiping it dry after cleaning will help to maintain the shine.
