How to Use

Before your first use, wash the tumbler thoroughly with warm water and a mild detergent. To maximize temperature retention, pre-heat the interior with hot water or pre-chill with ice water for a few minutes before adding your beverage. Fill the cup, leaving a small amount of space at the top for the lid. Ensure the spiral lid is tightened securely to activate the 360° leak-proof seal. The slim base is specifically designed to slide easily into car cup holders for convenient access while on the road.

Care & Safety

To preserve the integrity of the 7-layer thermal structure and the exterior finish, hand washing is highly recommended. Avoid using abrasive scrubbers or bleach-based cleaners that might damage the stainless steel. Do not place the tumbler in the microwave or freezer. When filled with boiling liquids, keep out of reach of children and open with caution to avoid potential steam burns. Always ensure the lid is properly aligned before tightening to prevent cross-threading.
