The Leak-Proof Thermos Mug is a stainless steel coffee mug with double walls that insulate the liquid inside. With a vacuum seal, this mug will keep your drink hot or cold for hours on end. Our double wall design prevents any leaks and makes it easy to clean.
1. Be sure to wash before use.
2. Overfill with hot liquids over 55℃(122℉) is recommended. Do not fill beyond 0.25”(7mm) below the bottom of the threads. Overfilling can lead to spills and scalding. To prevent spills, ensure the lid is assembled properly and fully tightened before use. Hot liquids can cause scalding.
3. Please be cautious when drinking hot liquid directly from your mug.
4. Do not use sealable items with carbonated or fermenting beverages or foods. Doing so may cause pressure buildup and lead to lid failure and spills, which can scald, or forceful ejection of lid and contents, which can cause injury.
