Tamba means "Copper". Drinking water out of a Tamba bottle has many benefits. When you store water in a copper vessel overnight or for more than 6-8 hours, the vessel releases ions into the water. Drinking this water can improve your overall health. Hence, it is important to store water in copper vessels for eight hours or more and not just drink from copper vessels. Drink this water in the morning and then sip throughout the day. Size: 1900 ml / 30 oz Dimensions: 3" x 10.5". Color: Copper. Material: Copper.
