Using your VitaJuwel ViA Heat Insulated Crystal Infusion Bottle is easy. First, if you want to make tea, add your tea leaves to the extra - large tea strainer (sold separately) and place it in the bottle. Then, fill the bottle with hot or cold water. You can leave the gemstone blend in the bottle to infuse the water with its special energy. When you're done using it, simply empty the bottle and clean it with mild soap and water. Make sure to dry it thoroughly to keep it in good condition. Avoid dropping the bottle as the glass may break. And always handle the gemstones with care to prevent scratches.
