1. Wash the flask thoroughly with warm, soapy water before using it for the first time.
2. Fill the flask with your desired beverage.
3. Screw on the lid tightly.
4. If you are using the flask for hot beverages, be sure to let the beverage cool slightly before pouring it into the flask. This will help to prevent the glass from cracking.
5. If you are using the flask for cold beverages, be sure to not fill it too high. This will help to prevent the beverage from spilling over when the flask is jostled.
6. Enjoy your beverage!
