Setup
Initial Cleaning
Before first use, wash all components of the tumbler, including the cup, lid, and straw, with warm soapy water. Rinse thoroughly and allow to air dry completely. This ensures hygiene and removes any manufacturing residues.
Lid and Straw Assembly
- Ensure the silicone seal on the lid is properly seated to prevent leaks.
- Place the lid onto the tumbler and twist or press down firmly until it is securely in place.
- Insert the straw through the designated opening in the lid. The straw is designed to be telescopic for convenience.

Operating Instructions
Filling the Tumbler
The wide mouth opening allows for easy filling with your preferred beverage. For hot liquids, do not close the lid immediately after pouring to prevent pressure buildup and potential burns from hot air. Allow a few moments for steam to escape before securing the lid.
Temperature Retention
This tumbler features a double-layer inner and outer 304 18/8 stainless steel cup with a vacuum insulation layer, enhanced by a 2-thickness copper coating. This design ensures excellent temperature retention.
- Cold Beverages: Keeps drinks cold for up to 9 hours.
- Hot Beverages: Keeps drinks hot for up to 5 hours.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Liquid leaking from lid | Lid not properly sealed; silicone ring dislodged or damaged. | Ensure the lid is securely twisted/pressed down. Check that the silicone seal is correctly seated and free from debris. If damaged, replace the lid. |
| Poor temperature retention | Lid not sealed; extreme external temperatures; tumbler damage. | Verify the lid is tightly closed. Avoid leaving the tumbler in direct sunlight or extreme cold for extended periods. Inspect for dents or damage that could compromise vacuum seal. |
| Exterior sweating | Compromised vacuum insulation; extreme temperature difference. | The tumbler is designed to be sweat-resistant. If sweating occurs, the vacuum insulation may be compromised, often due to impact damage. Contact support if the issue persists without visible damage. |
