Using your Lifeventure 1L High - Performance Wide Mouth Vacuum Flask is easy. First, unscrew the stopper to fill the flask with your desired hot or cold drink. You can use the retractable side handle for short - term carrying or attach the shoulder strap for longer trips. The stainless - steel lid can be used as a cup, and don't forget there's an extra cup inside. To keep it in good condition, clean the flask regularly with mild soap and warm water. Don't use abrasive cleaners as they may damage the copper coating. When not in use, keep the stopper loose to let air circulate and prevent odors. Also, make sure to store it in a cool, dry place.
