2. Setup
2.1 Unpacking
Carefully remove the mug and its lid from the packaging materials. Inspect all components for any signs of damage.
2.2 Initial Cleaning
Before the first use, it is recommended to wash the mug and lid thoroughly. Use warm water and a mild dish soap. Rinse all parts completely to remove any manufacturing residues. Allow the mug and lid to air dry completely before assembly.
3. Operating Instructions
3.1 Filling the Mug
- Unscrew the lid by twisting it counter-clockwise.
- Pour your desired hot or cold beverage into the mug.
- Do not overfill. Leave approximately 1 inch (2.5 cm) of space from the top rim to allow for the lid and prevent spills.

- Twist the lid clockwise until it is securely tightened. Ensure the lid is properly aligned and sealed to prevent leaks and maintain beverage temperature.

3.3 Drinking
The wide mouth design allows for direct drinking, similar to a traditional mug. This design is intended to enhance the aroma and taste experience of your beverage.
3.4 Temperature Retention
The mug is designed to keep beverages hot for up to 12 hours and cold for up to 24 hours. For optimal temperature retention, consider pre-heating the mug with hot water or pre-chilling with cold water for 5-10 minutes before adding your beverage.

4. Maintenance and Care
4.1 Daily Cleaning
After each use, disassemble the lid and wash all components with warm, soapy water. Rinse thoroughly.
4.2 Dishwasher Safety
The Fellow Carter mug and its lid are dishwasher safe. For best results, place them on the top rack of your dishwasher. The ceramic interior coating is designed to withstand dishwasher cleaning.
4.3 Drying and Storage
Ensure all parts are completely dry before reassembling and storing to prevent odor or mildew buildup. Store the mug with the lid slightly ajar to allow for air circulation.
4.4 Important Notes
- Do not use abrasive cleaners, scrubbers, or bleach, as these can damage the mug's finish or interior coating.
- Avoid placing the mug in a microwave or freezer.
5. Troubleshooting
5.1 Leakage
- Ensure the lid is securely tightened and properly aligned with the mug's threads.
- Check the silicone seal on the lid for any damage, tears, or misalignment. A damaged seal can compromise leak-proof performance.
- Avoid overfilling the mug beyond the recommended level.
5.2 Temperature Not Retained
- Verify that the lid is tightly sealed. A loose lid will quickly dissipate heat or cold.
- For optimal performance, ensure the mug was pre-heated or pre-chilled before adding your beverage.
- Extreme external temperatures (e.g., direct sunlight, very cold environments) can affect temperature retention.
5.3 Unpleasant Odor or Taste
- Thoroughly clean the mug and lid immediately after each use. Pay special attention to the lid's plastic components and seals, as these can sometimes retain odors if not cleaned promptly.
- For persistent odors, a mixture of baking soda and water can be used for soaking. Rinse thoroughly afterward.
5.4 Mug Does Not Fit in Car Cup Holder
The Carter Everywhere mug features a wide design, which may not fit all standard car cup holders. This is a design characteristic, not a product defect. Consider alternative carrying methods such as a backpack or bag.
