Using this bottle is easy. First, if you want to make infused 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 enjoy the beautiful sight of the gemstones inside while sipping your drink. Remember to clean the bottle regularly. Use mild soap and warm water to wash it. Don't use abrasive cleaners as they may damage the glass or the gemstones. Keep the bottle away from extreme temperatures and sharp objects to prevent cracks. Also, if you're using the tea strainer, make sure to dry it thoroughly after each use to avoid mold growth. With proper care, this bottle will serve you well for a long time.
