Our Travel Tumbler is 100% leakproof, so you don’t have to worry while you are on the go; in any case, we recommend not to overfill it.
To guarantee leakproofness make sure that your lid (Tumbler Coffee Lid, Tumbler Food Lid and Tumbler Sport Lid) is properly closed; screw it until the orange silicone seal disappears.
Avoid shaking Travel Tumbler, especially when using it with boiling-hot beverages drinks, as it may cause excessive pressure.
Keep away from kids when using Travel Tumbler with boiling-hot beverages.
Not intended for use with carbonated water.
