Drinking water from a copper vessel is an ancient Ayurvedic practice, and the infused water is considered medicine, called 'Tamra Jal'. Copper water is revered for its many health benefits and its naturally alkaline properties. Studies have shown that copper is anti-bacterial, anti-oxidant, improves immunity, prevents aging, eliminates toxins and free radicals, and stimulates the brain. Our Copper Hand-Hammered Cups are handcrafted with love by artisans in India using traditional techniques. Each of the bottles is shaped from a single sheet of 100% pure copper with no seams.
