Handcrafted, unlacquered pure copper (tamra) bottle for daily Ayurvedic hydration. Designed to prepare tamra-jala on the go. How to use Rinse well, fill with drinking water, and leave 6–8 hours (overnight is ideal). Sip at room temperature in the morning or through the day. Empty, rinse, and dry thoroughly after use. Care Hand-wash only. Clean occasionally with lemon + salt (or vinegar + salt); rinse and dry. Copper naturally develops a patina—this is normal and can be polished if you prefer shine. Do not use for acidic drinks, dairy, or hot liquids. Not dishwasher/microwave safe. Notes Capacity: 1 L. Made from 100% pure copper. For drinking water only. If you are on a copper-restricted diet, consult a professional.
