To prevent burns or injury, ensure that the lid is securely fastened before consuming hot beverages and take care when handling the tumbler, as the exterior may become hot. Always keep out of reach of children and use with adult supervision when necessary. We recommend allowing hot beverages to cool to a suitable drinking temperature before consuming directly from the tumbler. By using this product with hot liquids, you acknowledge and accept responsibility for any risks associated with its use. Stay safe and enjoy your drinks responsibly.
