Jiva copper water bottles are made of 100% pure copper. Tamra Jal (copper water) is beneficial in balancing all three doshas (vata, pitta & kapha) and is helpful in boosting overall health. Copper water is also known to be anti-microbial. The bottles are joint-free, leak-proof and coated outside with lacquer which prevents minor scratches. Jiva copper bottles are available in three finishes: hammered, matte finish and printed.
