How to use

Preheat or precool the thermos by rinsing it with hot or cold water before filling to improve temperature retention.

When pouring, unscrew the lid and pour directly or use the lid as a temporary cup if designed for that purpose.

Usage recommendations

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.
