How to Use and Maintain Your Product

Steps:

1. For optimal performance, preheat with hot water (for hot drinks) or prechill with ice water (for cold drinks) for 5 minutes.

2. Fill with your beverage, leaving minimal air space at the top.

3. Press the silicone stopper firmly to seal and prevent leaks.

4. Sip directly from the spout or use the handle for easy carrying.

5. Hand wash with mild soap and a soft brush; air dry thoroughly.

Pro Tip: Add ice cubes or boiling water for 5 minutes before use to boost temperature retention.
