How to use

Before first use, rinse the flask with warm water and mild detergent and allow it to dry. Pre-warm or pre-cool the flask by filling it briefly with hot or cold water, then emptying before filling with the beverage. Secure the screw-top closure firmly to minimise leaks, and open carefully to avoid steam when containing hot liquids. Clean after each use by rinsing with warm soapy water; avoid abrasive cleaners that could damage finishes. Allow the flask to dry completely with the lid removed before storing.

Usage recommendations

For optimal temperature retention, preheat or precool the flask for a few minutes before filling. Avoid using carbonated drinks that may cause pressure build-up and do not place the flask in a microwave. Regular cleaning and drying will maintain hygiene and performance.
