1. Wash before first use
   • Clean the flask with warm water and mild dish soap.
   • Rinse thoroughly and let it dry.
2. Preheat or precool (optional)
   • For hot drinks: Fill with hot water for 3–5 minutes, then empty it.
   • For cold drinks: Fill with cold water or ice water for 3–5 minutes, then empty it.
3. Fill the flask
   • Pour in your hot or cold beverage.
   • Leave about 1–2 cm of space at the top to make sealing easier.
4. Close the lid tightly
   • Screw the lid on securely to prevent leaks and maintain temperature.
5. Drink safely
   • If the beverage is very hot, pour a little into the cup (if the lid doubles as a cup) or let it cool slightly before drinking to avoid burns.

Care tips

• Hand wash is recommended unless the manufacturer states it's dishwasher-safe.
• Do not use bleach or harsh cleaners.
• Avoid putting the flask in a microwave or on a stove.
• Don't store milk, soup, or other perishable liquids for extended periods, as they can spoil.
• Leave the lid off when storing the flask after cleaning to prevent odors.
