2. Setup and First Use

1. Initial Cleaning: Before first use, wash the flask thoroughly with warm water and mild dish soap. Rinse completely to remove any manufacturing residues.
2. Drying: Ensure the flask is completely dry before storing or filling. Air dry with the cap off to prevent moisture buildup.

3. Operating Instructions

3.1 Filling the Flask

1. Unscrew the Cap: Twist the cap counter-clockwise to remove it. The integrated lanyard ensures the cap remains attached to the flask.
2. Pour Liquid: Due to the wide mouth opening, you can easily pour your desired liquid directly into the flask without the need for a funnel.
3. Do Not Overfill: Leave a small air gap at the top to prevent pressure buildup and ensure a secure seal.

3.2 Sealing and Transporting

1. Secure the Cap: Screw the cap clockwise until it is tightly sealed. The leak-proof design prevents spills during transport.
2. Carry Safely: The compact design allows the flask to be easily slipped into a pocket or bag.

3.3 Drinking from the Flask

1. Unscrew the Cap: Twist the cap counter-clockwise.
2. Drink Directly: The wide mouth design facilitates comfortable drinking directly from the flask.
3. Reseal: After drinking, screw the cap back on tightly to maintain the seal.

4. Maintenance and Care

1. Regular Cleaning: After each use, wash the flask with warm water and mild dish soap.
2. Drying: Always ensure the flask is completely dry before storing to prevent odors or mildew. Store with the cap off or slightly ajar to allow air circulation.
3. Avoid Harsh Cleaners: Do not use abrasive cleaners, bleach, or chlorine-based products, as these can damage the stainless steel finish.
4. Dishwasher Safety: This flask is not recommended for dishwasher use. Hand washing preserves the finish and integrity of the seal.

5. Troubleshooting

• Leakage: If the flask leaks, ensure the cap is screwed on tightly and the silicone seal inside the cap is properly seated and free from damage or debris.
• Difficulty Cleaning: For stubborn residues, use a bottle brush to reach all internal surfaces. A mixture of baking soda and water can help remove odors or stains.
• Cap Stuck: If the cap is difficult to open, try running the top of the flask under warm water for a few moments to expand the metal slightly.
