How to use
Preheat or precool the thermos by rinsing it with hot or cold water before filling to improve temperature retention. Open the screw-top closure, pour in the desired beverage, then close the lid firmly to secure the seal. Place the thermos upright in a cup holder or bag to minimize movement. When pouring, unscrew the lid and pour directly or use the lid as a temporary cup if designed for that purpose.
Usage recommendations
Hand wash recommended to maintain the vacuum integrity and exterior finish; avoid abrasive cleaners or bleach. Do not use in microwave ovens. For best results with hot drinks, preheat the flask; for cold drinks, prechill before filling. Regularly inspect the screw-top seal and replace if damaged to prevent leaks.
