A compact, pure tamra (copper) sphere for making tamra-jala anywhere. Drop it into a glass or jug of drinking water to emulate a copper vessel—perfect for travel or the office. How to use Rinse the ball. Place in a glass/jug of drinking water (250–1000 ml). Leave 4–8 hours (overnight is ideal), then remove the ball and sip the water. Dry the ball thoroughly after each use. Care Hand-wash only. Occasionally clean with lemon + salt (or vinegar + salt); rinse and dry well. Copper naturally develops a patina—this is normal and can be polished if you prefer shine. Store clean and completely dry. Notes & safety Made from 100% pure, unlacquered copper. For plain drinking water only; do not use with acidic drinks, dairy, or hot liquids. Not a toy—keep out of reach of children. If you have a copper-restricted diet, consult a professional.
