3. Operating Instructions
Filling the Tumbler
Fill the tumbler with your desired hot or cold beverage. Do not overfill; leave space for the lid to prevent spills.
Using the SmoothSip Spout
The SmoothSip spout is designed for comfortable, direct sipping. Simply bring the tumbler to your lips and drink. The design minimizes splashes during use.

Leak-Resistant Lid
The lid is engineered to be splash-resistant, helping to keep your drink contained within the tumbler. Ensure the lid is securely fastened to prevent accidental spills.

Temperature Retention
The double-wall insulation keeps hot beverages warm for up to 6 hours and cold beverages chilled for up to 24 hours. For best results with hot drinks, pre-warm the tumbler with hot water before filling. For cold drinks, pre-chill with ice water.

4. Maintenance
Cleaning
- Tumbler Body: Hand wash only. Do not place the stainless steel body in the dishwasher, as this may damage the finish and insulation properties.
- Lid: The lid is dishwasher-safe (top rack recommended).
- For thorough cleaning, ensure all parts are separated and cleaned individually.
Storage
Store the tumbler with the lid removed to allow for air circulation and prevent odors.
5. Troubleshooting
Lid Leaking/Splashing
- Ensure the lid is securely screwed onto the tumbler body.

Poor Temperature Retention
