A lovely solid copper tumbler. Matches very well with our copper carafe. People in India have been drinking, eating and cooking with copper vessels for hundreds of years, as copper has potent health benefits and antibacterial, antiviral, antimicrobial and anti-inflammatory properties. Water stored in pure copper absorbs all of the positive properties of the mineral, and will not become stale, even when stored for long periods of time. In fact, according to Ayurveda, water stored in a copper container has the ability to balance all the three doshas in your body. This water is known as tamara jal and is best consumed after having been in the copper vessel for at least eight hours. For water or other non-acidic becerages. Wash with mild soap and warm water. Made in India.
